$B$. Out of $P^{3-}, S^{2-}$ and $Cl^{-}$,$Cl^{-}$ ion is larger in size.

(B) For isoelectronic species,the size of the ion increases as the negative charge increases and decreases as the positive charge increases. Comparing $P^{3-}, S^{2-}$,and $Cl^-$,all have $18$ electrons. The size order is $P^{3-} > S^{2-} > Cl^-$. Therefore,the statement that $Cl^-$ is the largest is incorrect. Thus,option $(B)$ is the incorrect statement.

Assertion: The atomic radius of gallium is higher than that of aluminium.
Reason: The presence of additional $d$-electrons offers poor screening effect for the outer electrons from increased nuclear charge.
