Solution

The correct option is B

The formula of calcium hydroxide is $C a (O H)_{2}$ as in compounds formed with polyatomic ions.
The ion is enclosed in a bracket before writing the number to indicate the ratio.
In the case of calcium hydroxide the bracket around OH with subscript 2 indicates that there are two hydroxide groups joined to one calcium atom.
