What is tropism in plants related to?
Answer and explanation
Correct answer: Growth according to the direction of stimulus

Light, gravity, water, touch, and chemicals can act as stimuli. Therefore option A is correct; digestion, blood flow, and breathing rate are animal or physiological processes, not plant tropic growth.
