The correct answer is C. Portuguese.
The Portuguese were the last rulers of Goa. They ruled Goa from 1510 to 1961. The Portuguese first arrived in Goa in 1510, when they captured the city from the Sultanate of Bijapur. The Portuguese ruled Goa as a colony for over 450 years. During this time, they introduced Christianity to Goa and built many churches and monasteries. They also built a strong military presence in Goa, which helped to keep the city safe from attack.
In 1961, India invaded Goa and took control of the city. The Portuguese were forced to leave Goa, and the city became a part of India. Today, Goa is a state of India and is a popular tourist destination.
The other options are incorrect. The French ruled Pondicherry, the Dutch ruled Malabar, and the Britishers ruled Bengal.
