The correct answer is: C. Marcaim
Fort Aguada is a 16th-century Portuguese fort located in the village of Marcaim, Goa, India. It was built in 1540 by the Portuguese Viceroy Afonso de Albuquerque to protect the Portuguese settlements in Goa from the attacks of the Marathas and the Siddis. The fort is located on a hill overlooking the Arabian Sea and is one of the most popular tourist attractions in Goa.
The fort is a rectangular structure with four bastions at each corner. The walls of the fort are made of laterite stone and are about 10 feet thick. The fort has a moat around it and is entered through a gatehouse. The fort is now in ruins, but it is still an impressive sight.
The fort was originally named Forte de São Sebastião, but it was later renamed Fort Aguada after the nearby Aguada spring. The fort was used as a military base by the Portuguese until 1961, when Goa was annexed by India. The fort was then abandoned and fell into disrepair.
In the 1980s, the fort was restored by the Archaeological Survey of India. The fort is now open to the public and is a popular tourist destination. The fort offers stunning views of the Arabian Sea and the surrounding countryside.
The fort is also home to a number of museums, including the Goa State Museum, the Archaeology Museum, and the Military Museum. The fort is also a popular spot for picnics and other outdoor activities.
