King Cobra is the only snake that makes its own nest. Why does it make its nest ?

1. The question states that the King Cobra is the only snake that makes its own nest and asks why it does so. 2. King Cobras are unique among snakes for their nest-building behavior. 3. Option (A) is incorrect; while they are snake-eaters (ophiophagous), the nest is not primarily for attracting prey. 4. Option (B) is incorrect; King Cobras are oviparous (egg-laying), not viviparous (live-bearing). 5. Option (D) is incorrect; snakes do not build nests for hibernation; they seek existing shelters (hibernacula). 6. Option (C) is correct. The female King Cobra gathers leaves and debris to build a mound-like nest. She lays her eggs inside this nest and then guards it fiercely until they are hatched. This parental care (guarding the nest) is highly unusual for snakes.
