Solution

The correct option is A

Hydroxy, -ol


(a) Hydroxy, -ol

Wherenever -OH is not the primary functional group, it is treated as a substituent. As a substituent, it gets the prefix 'Hydroxy'.
When -OH is the primary functional group, it gets the suffix-'ol'

For example,

3-hydroxypropanoic acid

propan-2-ol or 2-propanol
