Answer 1

Answer:

c) Thigmotropism.

Explanation:

Thigmotropism is the movement that helps the climbing veins to find a suitable support. Thigmotropism is the plant response when there is any solid object near it, which allows it to cling to it.

It is a directional response of the plant that results in the differential growth of the plant due to the solid object in physical contact with it.
