Explanation:

To determine the correct answer, we analyze each option:

• Option A: The rate at which work is performed is power, not kinetic energy.
• Option B: Kinetic energy is defined as the energy an object possesses due to its motion. This matches the definition of kinetic energy.
• Option C: The mass of an object is a property related to matter, not energy, so this is incorrect.
• Option D: Energy that is stored is potential energy, not kinetic energy.

Answer:

B. energy that is due to motion
