The Answer is Al.
Valence electron:-
It is an outer shell electron with an atom, and that can participate in the formation of a chemical bond if the outer shell is not closed; in a single covalent bond, both atoms in the bond contribute one valence electron in order to form a shared pair.
Electronic configuration of Al:-
\([Ne] 3s^{2} , 3p^{1}\)
So, the valence electrons are 3 in the case of Al.
Hence, the correct option is Al.
