Option (b) is correct
- The king cobra (Ophiophagus hannah) is the only known snake species that constructs an elaborate, above-ground nest for its eggs. Using its body to gather leaves and twigs, the female builds a nest, lays up to 50 eggs, and guards it aggressively until they hatch, usually over 2–3 months.
