The only snake that builds a nest is

Result
Your answer: —  Â·  Correct: B
Explanation

The King Cobra (Ophiophagus hannah) is uniquely documented as a snake species that constructs an above-ground nest from leaf litter and other material and actively guards its eggs until shortly before hatching. Field and experimental studies report that females build and attend nests that provide warmer, more stable thermal regimes beneficial for hatching success, a behaviour not recorded for other snake species. Conservation and natural-history sources likewise note that nesting females can be highly defensive while protecting their clutches. These convergent reports identify the King Cobra as the only snake known to build and guard nests, supporting option 2 as correct [3].
