Vasco da Gama arrived in India in 1498 at Calicut. Calicut, also known as Kozhikode, is a city located in the present-day state of Kerala in southern India. It was an important trading port during that time and was known for its spices, especially pepper.
Option 1, Madras (now known as Chennai), is not the correct answer as Vasco da Gama did not arrive there in 1498. Madras became a major port only in the 17th century.
Option 2, Calcutta (now known as Kolkata), is also not the correct answer as Vasco da Gama did not reach that part of India during his voyage.
Option 4, Bombay (now known as Mumbai), is also not the correct answer as Vasco da Gama did not arrive in that area during his journey.
Therefore, the correct answer is Calicut.
