Taj Mahal is one of the most famous and iconic structures in the world. It is a white marble mausoleum located in Agra, India. While all the given options about the Taj Mahal are generally correct, the statement that is not correct is option B: "The names of artisans who built it are engraved on it."

Explanation:

The Taj Mahal was built by the Mughal emperor Shah Jahan in memory of his beloved wife, Mumtaz Mahal. It is widely regarded as a magnificent mausoleum and a masterpiece of Mughal architecture. However, the names of the artisans who built it are not engraved on the monument itself.

The Taj Mahal was constructed between 1632 and 1653, with thousands of skilled artisans, craftsmen, and laborers involved in its creation. The chief architect of the Taj Mahal was Ustad Ahmad Lahauri, who is known to have designed the structure. Other notable architects and artisans involved in the construction included Ismail Khan, Mir Abdul Karim, and Qazim Khan.

While the names of the architects and artisans are not engraved on the Taj Mahal, historical records and accounts provide information about their contributions. Some of these records mention the names of the artisans and craftsmen who worked on the mausoleum. The construction of the Taj Mahal involved a range of skilled workers, including calligraphers, stonecutters, mosaic artists, and craftsmen specializing in marble inlay work.

It is important to note that the Taj Mahal is adorned with intricate and exquisite calligraphy, which includes passages from the Quran. The calligraphy is a form of art in itself, but it does not specifically mention the names of the artisans involved in its creation.

In conclusion, while the Taj Mahal is indeed a magnificent mausoleum built by Shah Jahan, the statement that the names of the artisans who built it are engraved on it is not correct. The monument stands as a testament to the incredible craftsmanship and architectural prowess of the Mughal Empire, but the specific names of the artisans remain undocumented on the structure itself.
