Solution

The correct option is D Move away
Amoeba responds to stimuli, such as strong light, touch, and very warm or very cold temperatures. They respond to this by either moving away from the offending stimuli or rolling into a ball. No special sense organs but it exhibit generalized sensitivity e.g., avoids bright light (-ve phototaxis) and certain injurious chemical (-ve chemotaxis), moves away when touched (-ve thigmotaxis) and move towards food (+ve chemotaxis).
So, the correct answer is option D.
