Best answer
Correct option is (a) Visualize food

For explanation: The sensory system of earthworm lacks eyes. Hence, the earthworm cannot visualize its food. However, it contains receptor cells which helps it to detect vibrations, changes in light intensities and allows it to react to chemical stimuli.
