Solution

The correct options are
C
Pauli's exclusion principle

D
Afbau Principle

Pauli Exclusion principle can be stated as: "only two electrons may exist in the same orbital and these electron must have opposite spin.

Now, we can conclude that in s orbital only 2 electrons can be filled.

So 1 $s^{6}$ configuration violates Pauli Exclusion principle.
