Correct option is C
Explanation-
The Purple-rumped Sunbird (Leptocoma zeylonica) is native to the Indian subcontinent. It is nectarivorous (feeds on nectar) and is known to defend flower patches from other nectar feeders. This territorial behavior helps ensure a steady nectar supply and is a well-documented trait of sunbirds.

Option D - Crescent honeyeater – This bird is native to Australia and nearby regions, not India.
