Solution

The correct option is D
Analysing information given, we can conclude that compound should have:
i) Carboxylic group which can most readily give effervescence of $C O_{2}$ with $N a H C O_{3}$ .
ii) Acidic hydrogen which reacts with $N a$ metal to produce $H_{2}$ gas.
ii) $- O | | C - C H_{3}$ or $- C H_{2} - O H | C - C H_{3}$ residue to respond idoform test.

Compound in (d) validates the required.
