The correct answer is: George Thomas.
George Thomas was an Irish soldier of fortune who fought in the Indian subcontinent during the late 18th and early 19th centuries. He is best known for his role in the founding of the princely state of Jahazgarh (now in Haryana, India).
Thomas was born in County Clare, Ireland, in 1756. He joined the British East India Company in 1776 and served in the Seven Years’ War. After the war, he left the company and became a mercenary. He fought for various Indian rulers, including the Marathas and the Nizam of Hyderabad.
In 1790, Thomas founded the princely state of Jahazgarh. He ruled the state until his death in 1802. The fort of Georgegarh (Jahazgarh) was built by Thomas in 1792. It is located in the town of Jahazgarh, which is now in the district of Mahendragarh in Haryana, India.
The fort is a large, rectangular structure with four towers at each corner. It is made of red sandstone and has a moat around it. The fort is now in ruins, but it is still an impressive sight.
The other options are incorrect because they are not the names of the person who built the Fort of Georgegarh (Jahazgarh) in Haryana.
