The correct option is (d) autonomic movement of growth.

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 on one side -causes the organ to bend to the opposite side.
