Two electrons are found in the same atom. one has the quantum number set (3, 2, 0, +½), and the other has the quantum number set (3, 1, 0, +½). they share the
a same sub level but differentt orbitals
b same orbital but different spin directions
c same energy level but different sublevels
d same type of sub level but found in different energy sub levels

Explanation: In an atom, there is a nucleus at the center that has protons and neutrons inside it and the electrons are present in different shells(energy levels) around the nucleus. These shells(energy levels) are divided into sub shells(sub energy levels).

To know more about the position and other information about an electron present in an atom we use a set of four numbers known as quantum numbers.

The four quantum numbers are:

principal quantum number:- It's denoted by n and it has an integer values 1, 2, 3 and so on. It's tells us about the shell in which an electron is present.

Azimuthal  or orbital angular momentum quantum number :- It's denoted by l and its values are (n-1), where n is principal quantum number.

for example, if n = 1 then l = 0

n = 2 then l = 0 or 1

n = 3 then l = 0, 1 or2

and n = 4 then l = 0, 1, 2 or 3

l = 0 indicates the electron is in s subshell.

l = 1 indicates the electron is in p subshell.

l = 2 indicates the electron is in d subshell and

l = 3 indicates the electron is in f subshell.

Magnetic quantum number :- It's denoted by ml and it has values from -l to +l values.

It determines the number of orbitals and their orientation within a subshell.

for example, l = 0 then ml = 0

l = 1 then ml = -1, 0, +1

l = 2 then ml = -2, -1, 0, +1, +2

l = 3 then ml = -3, -2, -1, 0, +1, +2, +3

Spin quantum number :- It is denoted by ms and it does not depend on other quantum numbers. It tells us if the spin of an electron is clockwise or counter clockwise.

it has +1/2(clockwise) or -1/2(counter clockwise) values.

The four quantum numbers are written in the order n, l, ml and ms.

If we look at the given two sets of quantum numbers then values of n, ml and ms are same but the value of l is different.

Value of n is same means both electrons are in same energy level. Value of ms is same means the spin of both the electrons is same.

Value of l for the first set is 2 means the electron is present in d-subshell. Value of l for the second set of quantum numbers is 1 means the electron is present in p-subshell.

choice A is not correct as the electrons are in different subshells.

Choice B is also not correct as the electrons spin is in same direction.

Choice C is correct as the electrons are in same energy level but different sublevels.
