ASSERTION (A) : Two electrons in an atom can have the same values of four quantum numbers.

REASON (R) : Two electrons in an atom can be present in the same shell, subshell and orbital and have the same spin.

View answer and explanation

Correct option: D

A

and

R

both are wrong.

Option D (If A and R both are wrong) is correct because Assertion (A) is wrong due to Pauli Exclusion Principle, and Reason (R) is also wrong because electrons in the same orbital must have opposite spins.
