(B) secondary alcohol is one where the $-OH$ group is attached to a carbon atom that is bonded to two other carbon atoms.Analyzing the structures:$(I)$ Contains two primary alcohols $(-CH_2OH)$.$(II)$ Contains a secondary alcohol (the $-OH$ is on a $CH$ group bonded to two carbons).$(III)$ Contains a tertiary alcohol (the $-OH$ is on a carbon bonded to three other carbons).$(IV)$ Contains secondary alcohols (the $-OH$ groups are on $CH$ groups bonded to two carbons).$(V)$ Contains a secondary alcohol (the $-OH$ is on a $CH$ group bonded to two carbons).$(VI)$ Contains tertiary alcohols (the $-OH$ groups are on carbons bonded to three other carbons).Thus, compounds $(II)$, $(IV)$, and $(V)$ contain at least one secondary alcohol.There are $3$ such compounds.

From the following, how many compounds contain at least one secondary alcohol? Choose the correct answer from the options given below:
