Solution

The correct option is B $C a (O H)_{2}$
Calcium hydroxide consist of calcium ion and hydroxide ion i.e. $C a^{2 +}$ and $(O H)^{-}$ , which have a charge of +2 and -1 respectively.
$\begin{matrix} Symbol & Ca & OH Charge & +2 & -1 \end{matrix}$
On cross-multiplication and balancing the charge, we get the formula as $C a (O H)_{2}$ .
