The correct answer is Option 3: Both 1 and 2.

1. Salt-water crocodile is found in the Andaman and Nicobar Islands.

This statement is correct. The saltwater crocodile (Crocodylus porosus) is indeed found in the Andaman and Nicobar Islands, which are a group of islands located in the Bay of Bengal, belonging to India. The saltwater crocodile is the largest living reptile and is known for its ability to survive in both saltwater and freshwater habitats. It is native to the coastal areas of the Indian subcontinent, Southeast Asia, and Northern Australia, including the Andaman and Nicobar Islands.

2. Shrew and tapir are found in the Western Ghats of the Malabar region.

This statement is also correct. The Western Ghats is a mountain range that runs parallel to the western coast of India, covering states such as Kerala, Karnataka, Tamil Nadu, and Maharashtra. The Malabar region is a part of the Western Ghats, located primarily in the state of Kerala. Both shrews and tapirs can be found in the Western Ghats, including the Malabar region.

Shrews are small, insectivorous mammals belonging to the family Soricidae. In the Western Ghats, you can find various species of shrews, such as the Malabar shrew (Suncus malayanus), a common shrew species found in the region.

Tapirs are large, herbivorous mammals known for their unique appearance, with a long, flexible snout resembling a mini-trunk. In the Western Ghats, the Malabar or Asian tapir (Tapirus indicus) can be found. It is the largest land mammal native to the region and is classified as an endangered species.

To summarize, both statements are correct. The salt-water crocodile is found in the Andaman and Nicobar Islands, while shrews and tapirs are found in the Western Ghats, including the Malabar region.
