Answer 2

Answer:

(d)

Explanation:

Both a and c are correct

Energy state, also called Energy Level, in physics, any discrete value from a set of values of total energy for a subatomic particle confined by a force to a limited space or for a system of such particles, such as an atom or a nucleus.

In chemistry, an electron shell, or energy level, may be imagined as an orbit with electrons around the nucleus of an atom. The closest shell to the nucleus is called the “K shell” followed by the “L shell” then the “M shell” and so on away from the nucleus. The shells can be denoted by alphabets (K, L, M, …)
