c
A is acidic so it belongs to the right side of table and $X$ belongs to the left side of table.
A is acidic so it belongs to the right side of table and $X$ belongs to the left side of table.
The electronegativities decrease from $X$ to $Y$ to $Z$.
The atomic radius increases in the order $X , Y$ and $Z$ and $X , Y$ and $Z$ could be phosphorus, aluminium and sodium respectively.
