Consider the following statements regarding the Indian squirrels : 1. They build nests by making burrows in the ground. 2. They store their food materials like nuts and seeds in the ground. 3. They are omnivorous. How many of the above statements are correct?

The correct option is (a) because only statement 3 is accurate; Indian squirrels, such as the common Three-striped Palm Squirrel, are omnivorous, consuming insects, bird eggs, and small reptiles alongside nuts and fruits. Statement 1 and 2 are incorrect because Indian palm squirrels are arboreal, building nests (dreys) in tree branches rather than burrowing, and they do not typically cache food underground. This question tests the core concept of the ecological niches and behavioral adaptations of common Indian fauna.
