Correct option is D)

Hint

Quantum number: It is defined as the set of numbers which describes the position and energy of electrons in an atom. There are four quantum numbers: principal, azimuthal, magnetic and spin quantum numbers.

Explanation

Step 1: Determine the maximum number of subshells

The principle quantum number () describe the distance between the nucleus and the electrons.
The azimuthal quantum number () is given by ()

We know that the maximum number of subshells is equal to is .

Step 2: Determine the maximum number of electrons in a subshell
Maximum electrons a subshell can accommodate is

Therefore, the total number of electrons in a subshell is

Thus, maximum number of electrons in a subshell is

Final answer

The correct answer is option (D).
