Solution

The correct option is A Autonomic
Autonomic movement is the spontaneous movement of the protoplasm seen in aquatic plants due to internal stimulus. It is not related to the external stimulus. Movement of cilia and flagella is an example of autonomic movement. A movement shown by a plant part in response to an external factor is called as paratonic movement. In this, the direction of movement is controlled by the direction of the stimulus. Mechanical movements are seen by non-living organs of plants due to hygroscopic changes.
Thus, the correct answer is option A.
