A carboxylic acid (X) of unknown structu...

A carboxylic acid (X) of unknown structure was found to contain only C, H and O. Titration data : 150 mg required 11.9 ML of 0.22 N NaOH to reach equilibrium point. Gentle heating of 'X' led to evolution of `CO_2` and formation of a new carboxylic acid, 'Y' with equivalent weight 74. Correct statement is/are

A

X is `HO_2 C-underset(CH_3)underset(|)CH-CO_2 H`

B

Y is `H_3 C -overset(O)overset(||)C-CH_2 - CO_2 H`

C

Y is `CH_3-CH_2-COOH`

D

X is `H_2 OC - CH_2 -overset(O)overset(||)C-CH_2-CO_2 H`
