(B) In the complex $[AlCl(H_2O)_5]^{2+}$,let the oxidation state of $Al$ be $x$.The oxidation state of $Cl^-$ is $-1$ and $H_2O$ is a neutral ligand $(0)$.$x + (-1) + 5(0) = +2$$x - 1 = +2$$x = +3$Thus,the oxidation state of $Al$ is $+3$.The covalency (coordination number) is the total number of coordinate bonds formed by the central metal atom with the ligands.Here,$Cl$ provides $1$ bond and $5$ $H_2O$ molecules provide $5$ bonds.Total covalency $= 1 + 5 = 6$.

The oxidation state and covalency of $Al$ in $[AlCl(H_2O)_5]^{2+}$ are respectively
