Overview:
The Malabar Coast is located in South India, specifically along the western side of the Indian subcontinent. It is a region known for its beautiful beaches, diverse ecosystems, and historical significance. The correct answer to the given question is option 'C' - Western Ghats.

Explanation:
The Malabar Coast is a stretch of coastline that runs parallel to the Western Ghats. Let's understand the options provided and why the correct answer is the Western Ghats.

a) Eastern Ghats:
The Eastern Ghats are a mountain range that runs along the eastern side of the Indian subcontinent. It stretches from Odisha in the north to Tamil Nadu in the south. The Malabar Coast is not located along the Eastern Ghats, so option 'A' is incorrect.

b) South India:
While the Malabar Coast is indeed located in South India, option 'B' is not the correct answer as it does not specifically mention the Western Ghats.

c) Western Ghats:
The Western Ghats, also known as the Sahyadri Mountains, are a mountain range that runs parallel to the western coast of India. It spans several states, including Kerala, Karnataka, Tamil Nadu, Maharashtra, and Goa. The Malabar Coast lies along this mountain range, making option 'C' the correct answer.

d) None of these:
Option 'D' is incorrect as the Malabar Coast does lie along the Western Ghats.

Therefore, the correct answer to the question "Where does the Malabar Coast lie?" is option 'C' - Western Ghats.
