C Correct answer
Explanation

Pulse plants (legumes like beans, lentils, peas) have root nodules containing nitrogen-fixing bacteria that convert atmospheric nitrogen into usable forms. Green, flowery, and non-green plants don't necessarily have this association - only legumes among pulses have this specialized nitrogen-fixing ability.
