Golghar is a historic granary located in Patna, the capital city of Bihar, India. It was built in the 18th century to address the recurring famines that plagued the region. The correct answer to the question is option 'D', which states that none of the given options are correct.

Here is an explanation of why none of the options mentioned in the question built the Golghar:

1. Warren Hastings: Warren Hastings was the first Governor-General of Bengal from 1773 to 1785. While he played a significant role in the administration and governance of Bengal, there is no record of him being involved in the construction of Golghar.

2. Lord Harding: There is no historical figure named Lord Harding associated with the construction of Golghar. It is possible that a typographical error occurred, and the intended name was Lord Hardinge, who served as the Governor-General of India from 1910 to 1916. However, this is still incorrect, as Golghar was constructed much earlier.

3. William Max: There is no historical figure named William Max associated with the construction of Golghar. It is possible that a typographical error occurred, and the intended name was William Maclure, an American geologist and philanthropist. However, he is not connected to the construction of Golghar.

4. John Garstin: John Garstin, an engineer in the British East India Company, is the actual person responsible for the construction of Golghar. He designed and oversaw the construction of Golghar in 1786-1787. Garstin designed it in the form of a large beehive-shaped structure with thick walls to store grains during times of excess production. However, due to flaws in its design, it was never fully utilized for its intended purpose.

In conclusion, the Golghar in Patna was built by John Garstin, an engineer in the British East India Company. The other options mentioned in the question are incorrect, as there is no historical evidence to support their involvement in the construction of Golghar.
