Answer 1

The correct option is D Shoot shows positive phototropism.

Phototropism is the type of tropic movement which occurs in response to light. Shoot of the plant is exposed to light and bends in direction of light. Hence, it shows positive phototropism. Root of the plant is not exposed to light and bends in opposite direction of light. Hence, it shows negative phototropism.
