Answer: (d) None.
None of the statements regarding Indian squirrels is correct.
Explanation:
Indian squirrels, specifically the Indian palm squirrel (Funambulus spp.), do not build nests by making burrows in the ground. Instead, they build nests called dreys in tree branches or crevices. They construct these nests using leaves, twigs, and other plant materials.
Indian squirrels do not store their food materials like nuts and seeds in the ground. They are known for their habit of caching food, but they usually store their food in tree crevices, hollows, or within their nests.
Indian squirrels are primarily herbivorous, not omnivorous. They primarily feed on plant matter such as fruits, nuts, seeds, flowers, and tender shoots. While they may occasionally consume insects or small invertebrates, their diet is predominantly vegetarian.
