The ancient port city of Muziris, famed for its trade connections, is located near modern-day:

Kollam
Kochi
Kodungallur
Kozhikode

The correct answer is C) Kodungallur.

Muziris was an ancient port city on the Malabar Coast of India. It was a major trading center between the Roman Empire and India, and was known for its spices, ivory, and other goods. The city was destroyed by a tidal wave in the 14th century, but its ruins have been excavated and are now a popular tourist destination.

Kodungallur is a town in Kerala, India, that is located near the ruins of Muziris. It is a major center for trade and commerce, and is also home to a number of historical and cultural sites.

The other options are incorrect because they are not located near the ruins of Muziris. Kollam is a city in Kerala, India, that is located on the Arabian Sea. Kochi is a city in Kerala, India, that is located on the Malabar Coast. Kozhikode is a city in Kerala, India, that is located on the Malabar Coast.
