D. autonomic movement of growth

Answer

D

Explanation

Opening of floral buds into flower is a type of autonomic movement of growth (nastic movement). This is non-directional movement in which the response is determined by the structure of the responsive organ and not to the direction of stimulus. Greater growth one side causes the organ to bend to the opposite side.
