Explanation:
Correct Answer: B. Respire

Reason:
Respiration is a fundamental process that occurs in all living organisms, including plants, animals, fungi, and microorganisms. It involves breaking down food to release energy necessary for life processes.

Breakdown of other options:
- A. Photosynthesize – Only in green plants, algae, and some bacteria.
- C. Move – Not all living things show visible movement (e.g., plants).
- D. Feed – All need nutrients, but not all feed in the same way (e.g., plants make their food).
- E. Transpire – Specific to plants.

So, the only process shared by *all* living things is respiration.
