Solution

The correct option is A Principal
Quantum numbers indicate the probability of finding an electron in the space around the nucleus. The different types of quantum numbers are principal, angular-momentum, magnetic and spin.

The principal quantum number determines the overall size and energy of an orbital. It is denoted by " $n$ ". The possible values of n are 1, 2, 3, and so on.
