Final answer:
The compound has three functional groups: a hydroxyl group, a carbonyl group, and an amino group. option c is correct.
Step-by-step explanation:
The compound described consists of several functional groups: an OH group (which is an alcohol functional group), a double bond to an oxygen atom (which could be a carbonyl group if it is part of an aldehyde or ketone or a carboxylic acid group), and an NH-2 group (which is an amino functional group).
Considering the structural hints provided, the compound features an OH group bonded to a carbon atom that is also double-bonded to an O atom and extends to an amino group (NH-2) through a chain of single bonds. We can identify the OH group as a hydroxyl functional group, the carbon double-bonded to an O as a carbonyl functional group, and the NH-2 group as an amino functional group. Therefore, the compound contains three functional groups.
