hope that helps

Explanation:
I think it is C because photosynthesis converts solar energy
Answer:
B. Excited state
Explanation:
Energy levels higher than the ground state are called the excited states. This concept is based on the premise that electrons can move round the nucleus in certain permissibe orbits or energy levels.
The ground state is the lowest energy state available to the electron. This is usually the most stable state.
The excited state is any level higher than the ground state. An electron in an energy level has a definite amount of energy associated with it at that level.
Electrostatic forces work on anything that is charged.
<span>Usually only protons and electrons, but also some other elementary particles.
