Which option correctly identifies tropism on the basis of stimulus?
Answer and explanation
Correct answer: प्रकाशानुवर्तन में प्रकाश, जलानुवर्तन में जल और रसायनानुवर्तन में रसायन उद्दीपन हैं
The governing concept is tropism, a directional growth response of a plant part to an external stimulus. Phototropism is caused by light, hydrotropism by water, and chemotropism by chemicals, so option A correctly matches each term with its stimulus. Option B swaps the stimuli, option C confuses chemicals with gravity, and option D incorrectly limits all tropisms to touch.
