DifficultConsider the following four elements which are represented according to the long form of the periodic table. Here $W, Y$ and $Z$ are left,up and right elements with respect to the element $X$. $Y$ belongs to the $16^{th}$ group and $2^{nd}$ period. Then,according to the given information,identify the incorrect statement regarding the given elements.
- AMaximum electronegativity $: Y$
- BMaximum catenation property $: X$
- CMaximum electron affinity $: Z$
- D$Y$ exhibits maximum electron affinity
