Answer
Primary
Work Step by Step
1) Identify the carbon atom directly attached to the "OH" group
2) Then count the number of alkyl groups connected to this carbon atom ( Hydrogen atoms does not count )
1 substituent - primary
2 substituents - secondary
3 substituent - tertiary
In this problem carbon atom attached to the "OH" has two hydrogen atoms and only one "R" - cyclohexyl group, that is why alcohol is primary
