Explanation:

- Coromandel Coast: Refers to the southeastern coast of India that stretches across Tamil Nadu and Andhra Pradesh. It is part of the East Coast.

- Malabar Coast: Lies along the southwest coast of India, primarily in Kerala. This is not part of the East Coast.

- Utkal Coast: Located in the northeast along the coast of Odisha, it forms a segment of the East Coast.

- Tamil Nadu Coast: Though not a formal term, it refers to the coast along Tamil Nadu, which is part of the East Coast.

Your initial thought was spot on. The Malabar Coast is indeed on the southwest side of India.
