The following acids have been arranged in the order of decreasing acid strength. Identify the correct order.
$I$. $ClOH$
$II$. $BrOH$
$III$. $IOH$

Considering the elements $B, C, N, F,$ and $Si,$ the correct order of their non-metallic character is:
$(a)$ $B > C > Si > N > F$
$(b)$ $Si > C > B > N > F$
$(c)$ $F > N > C > B > Si$
$(d)$ $F > N > C > Si > B$

Consider 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 $X$,and $X$ belongs to the $16^{th}$ group and $3^{rd}$ period. Then,according to the given information,the incorrect statement regarding the given elements is:

$Be$ and $Al$ show similarities in properties due to the diagonal relationship except in the property $X$ given below. What is $X?$
