Answer:
correct answer is A
Explanation:
Functional group:
The properties of organic compounds are depending on some groups of atom, which is known as functional group. Thus, the compounds, which have same functional group, have similar properties.
For example if the compound contains at least one double bond means it is an example of alkene.
Amines: Amines contain the characteristic –NH2 functional group.
Amine means R-NH2
Methyl amine means CH3NH2
Because meth means one carbon atom only and amine means –NH2 as functional group.
Therefore the correct answer is A
