options:

• protons and neutrons
• atoms or molecules
• electrons only
• waves

Explanation:

Thermal energy is related to the motion of the particles that make up a substance. Atoms or molecules are the basic particles of substances, and their kinetic energy contributes to thermal energy. Protons/neutrons are in the nucleus and don't directly contribute to thermal motion in this context, electrons alone or waves don't fit the definition of thermal energy's particle - based kinetic energy source.

Answer:

B. Atoms or molecules
