(D) Given that $X$ is in the $16^{th}$ group and $3^{rd}$ period,$X$ is Sulphur $(S)$.Based on the relative positions:$Y$ is above $X$ in the same group ($16^{th}$ group,$2^{nd}$ period),so $Y$ is Oxygen $(O)$.$W$ is to the left of $X$ in the same period ($15^{th}$ group,$3^{rd}$ period),so $W$ is Phosphorus $(P)$.$Z$ is to the right of $X$ in the same period ($17^{th}$ group,$3^{rd}$ period),so $Z$ is Chlorine $(Cl)$.Evaluating the statements:$(a)$ Electronegativity order: $O > Cl > S > P$. Thus,$Y$ $(O)$ has the maximum electronegativity. (Correct)$(b)$ Catenation property order: $S > P > O > Cl$. Thus,$X$ $(S)$ has the maximum catenation property. (Correct)$(c)$ Electron affinity order: $Cl > S > O > P$. Note: $Cl$ has higher electron affinity than $O$. Thus,$Z$ $(Cl)$ has the maximum electron affinity. (Correct)$(d)$ Oxygen $(Y)$ has no $d$-orbitals and can only exhibit a covalency of $2$. It does not exhibit variable covalency. (Incorrect)Therefore,the incorrect statement is $(d)$.
