Solution

The correct option is C 4-oxopentanoic acid
Answer:- 4-oxopentanoic acid
$5 C H_{3} -^{4} O | | C - 3 C H_{2} - 2 C H_{2} -^{1} O | | C - O H$
Since the parent chain has 5 carbon atoms, root word will be pentane and according to the priority of functional groups, -COOH Is the principal functional group in preference to carbony group thus naming will start from -COOH side.
Hence the correct IUPAC name is 4-oxopentanoic acid.
