Solution
The correct option is C Thigmonasty
Thigmonasty is the movement in response to touch. The most common example of thigmonasty is shown by the Mimosa plant when the leaves are touched. The stimulus in the form of touch causes folding of the leaflets due to the change in the turgor pressure and this effect is passed on to the entire branch and then whole plant and all the leaflets close. Thus, the correct answer is option D.
