Correct Answer: C
Solution :
Thigmotrophic movement (haptotropic movement) takes place in response to a touds or contact stimulus, in which more growth takes place on opposite side of touch, e.g., tendrils, tentacle of Drosera. Geotropism movement is shown by movement in roots. The leaves of sensitive plant Mimosa pudica (touch-me-not) show seismonasty (shodck movement) in response to physical contact injury, electric current, etc. It consists of folding and drooping of leaves. Tentacles of Drosera (insectivorous plant) and leaf lobes of Dionaea (insectivorous plant bend in response to contact by insects. This is called thigmonastic or haptonastic movements.
