The IUPAC name of $NC - CH X_{2} - CH X_{2} - COOH$ is:

A3-cyanobutanoic acid
B2-cyanopropanoic acid
C3-carboxypropanenitrile
D3-cyanopropanoic acid

Answer: D

The acid outranks the nitrile, so the name is that of a propanoic acid (three carbons including COOH). The -CN is a prefix cyano on C-3. The name is 3-cyanopropanoic acid.
