Answer 1

The Correct Option is A

Step 1: Define land-locked harbour.
A land-locked harbour is one that is surrounded by land on most sides, with only a narrow opening to the sea. It provides natural protection from winds and waves, making it safe for ships.

Step 2: Analyze the options.
- (A) Vishakhapatnam → It is a natural, land-locked harbour on the east coast of India. Hence, correct.
- (B) Marmagoa → This is an important port in Goa but not land-locked.
- (C) Mumbai → It is a natural harbour but not land-locked.
- (D) Chennai → It is an artificial port, not a land-locked harbour.

Step 3: Conclusion.
Among the options, Vishakhapatnam is the only land-locked harbour.
