Answer: Option (a) is the correct answer.
Explanation:
Every orbit has a fixed value of energy which means that energy is quantised. When heat is absorbed by the atom then the electrons go from low energy level to high energy level.
Whereas when heat or energy is released by the atom then electrons move from high energy level to low energy level. As a result, this heat is released in the form of visible light.
Thus, we can conclude that the statement when an electron drops down from a high energy level to a lower one, light energy is emitted, is true according to the quantum model of the atom.

The process of photosynthesis is when green plants and other living things transform light energy into chemical energy. The goal of photosynthesis is to convert Radnet energy from the sun to chemical energy for food.
