Solution

The correct option is A Mimosa
Mimosa plant show movement in the response to touch. It is also known as 'Touch me not pant'.
The reason for this response is as followed:
When the plant is touched, due to higher pressure at that point, the cells of leaf loose water to the adjacent cells.
This decreases turgor pressure and the cell becomes flaccid. Thus, causes the closure of leaves.
