d nuclear energy

Explanation:

To determine the form of electromagnetic energy, we analyze each option:

• Thermal energy is related to heat (molecular motion), not electromagnetic.
• Light energy is part of the electromagnetic spectrum (photons, electromagnetic waves).
• Sound energy is mechanical (vibrations in matter), not electromagnetic.
• Nuclear energy involves atomic nuclei (fission/fusion), not electromagnetic.
