None of the above

Detailed explanation-1: -Therefore, N shell has maximum energy associated with it as it is the farthest.
Detailed explanation-2: -The electrons in the energy level farthest from the nucleus are called valence electrons.
Detailed explanation-3: -Electrons with the highest energy levels exist in the outermost shell of an atom and are relatively loosely bound to the atom. This outermost shell is known as the valance shell and electrons in this shell are called valance electrons.
Detailed explanation-4: -Chemists use an “n” value, or the letters K, L, M, N, O, P, and Q. The “K” shell is the one closest to the nucleus, and “Q” is the farthest away. For simple atoms, those “n” values usually match the row number on the periodic table and are also known as energy levels.
Detailed explanation-5: -The third shell can hold 32 electrons. Within the shells, electrons are further grouped into subshells of four different types, identified as s, p, d, and f in order of increasing energy.
