Answer: C

Solution: Pea plants grow in winters when the days are shorter and the exposure to sunlight is less. Tendrils are hair-like structures that grow with the help of any support so, they are not seen to grow with the impact of gravity.  

On the other hand, tendrils that come in contact with the side of the object grows slowly and the side opposite to it is seen to grow at a very fast rate which causes rapid division of cells on the opposite side. This causes tendril to bend to the side where it touches the object and helps in clinging and does not flow with the wind.
