Answer:
A.
Explanation:
The quantum numbers that are used in the identification of an electron are n, l, m, and s.
n= principle quantum number
l= azimuthal quantum number
m= magnetic quantum number
s= spin quantum number
All the orbitals in a given subshell have the same value of n(principle quantum number) and l( azimuthal quantum number). Thus, the correct option is A.
