Jantar Mantar is a collection of architectural astronomical instruments built by Maharaja Sawai Jai Singh II, the ruler of Amber, in the early 18th century. These observatories were built in multiple locations across India to facilitate the study of astronomy and the measurement of time and celestial movements. The correct answer is option D, which includes all five locations where Jantar Mantar observatories were built: Delhi, Jaipur, Varanasi, Ujjain, and Mathura.

- Delhi: The Jantar Mantar in Delhi is the oldest of the five observatories built by Maharaja Jai Singh II. It was constructed in 1724 and is located near Connaught Place. The observatory in Delhi consists of several instruments, including the Samrat Yantra, the largest sundial in the world, and the Jai Prakash Yantra, which measures the position of celestial bodies.

- Jaipur: The Jantar Mantar in Jaipur is one of the most famous and well-preserved observatories. It was completed in 1734 and is a UNESCO World Heritage Site. The Jaipur observatory features a collection of 19 instruments, including the world's largest stone sundial called the Samrat Yantra. Other notable instruments include the Jai Prakash Yantra, the Ram Yantra, and the Narivalaya Yantra.

- Varanasi: The Varanasi observatory, also known as the Man Mandir Observatory, was built by Maharaja Jai Singh II in the early 18th century. It is located on the roof of the famous Man Mandir Palace in Varanasi. Although this observatory is relatively smaller compared to the ones in Delhi and Jaipur, it still houses several instruments, including the Digamsa, the Kranti, and the Disha Yantras.

- Ujjain: The Ujjain observatory, known as the Vedh Shala, was built by Maharaja Jai Singh II in 1725. It is situated in the town of Ujjain in Madhya Pradesh. The Vedh Shala consists of several instruments, including the Samrat Yantra and the Nadi Valaya Yantra, which are used for measuring time and celestial positions.

- Mathura: The Mathura observatory, also known as the Yantra Mandir, was built by Maharaja Jai Singh II in the early 18th century. It is situated in the city of Mathura in Uttar Pradesh. The instruments in this observatory are similar to those found in the other Jantar Mantar sites and are used for astronomical observations and calculations.

In conclusion, Maharaja Sawai Jai Singh II built astronomical observatories (Jantar Mantar) in all five locations mentioned: Delhi, Jaipur, Varanasi, Ujjain, and Mathura. These observatories were designed to study and observe celestial movements and were significant contributions to the field of astronomy.

  • Maharaja Sawai Jai Singh II (1686-1743) was the ruler of the Rajput State of Amber in India. A feudatory of the Mughals, he received the title of 'Sawai' (one and a quarter) from Emperor Aurangzeb, who declared him a quarter superior to his famous forebearer Mirza Raja Jai Singh (d. 1667) after he captured the Fort of Vishalgarh from the Marathas in 1701.
  • After bringing to the Emperor's notice some astronomic discrepancies that possibly affected the timings of Hindu and Muslim holy events and expressing his desire to correct these, Jai Singh also received Imperial backing for building his Astronomy Observatories at Delhi, Jaipur, Varanasi, Ujjain, and Mathura.
    • All except the observatory at Mathura are in existence today.
  • Sawai Jai Singh's ingenuity led to the invention of several outsize masonry instruments, the majority of which were used to determine the coordinates of celestial objects with reference to the local horizon.
    • During Jai Singh’s lifetime, the observatories were used to make observations in order to update existing ephemerides such as the Zīj-i Ulugh Begī.
    • Jai Singh established communications with European astronomers through a number of Jesuits living and working in India. In addition to dispatching ambassadorial parties to Portugal, he invited French and Bavarian Jesuits to visit and make use of the observatories
  • Jai Singh wrote the astronomical work 'Zij-e-Muhammad-Shahi' (Muhammad Shah's astronomical tables) in 1728. That same year he also built his new, magnificently designed capital Jaipur, about 200 km southwest of Delhi and constructed by combining the aspects of the ancient Hindu treatise on architecture, the Shilpa Shastra, and plans of many European cities of the period with Jai Singh's own ideas.
  • The European travelers of the time, like the Frenchman Louis Rousselet, and the English bishop, Heber, were greatly impressed by Jai Singh's unparalleled excellence in city planning.
  • Hence option (d) is the correct answer.
