Explanation / Answer

Amines are of the form RNH2 i.e. a derivative of ammonia in which one H of ammonia replaced by alkyl group. Therefore, the functional group in the triangle is a amine group with R = CH2COOCH2CH2CH(CH2OCH3)CONH2 .

Esters have the general formula RCOOR`.Therefore, the functional group in the square is a ester group with R = NH2CH2 and R` = CH2CH2CH(CH2OCH3)CONH2.

Ethers have the general formula ROR`.Therefore, the functional group in the pentagon is a ether group with R = .NH2CH2COCH2CH2CH(CONH2) and R` = CH3.

Amides have general formula RCONH2. Therefore, the functional group in the circle is a Amide group with R = NH2CH2COCH2CH2CH(CH2OCH3).

Hence, the correct answer is option C.
