A mixture of carboxyliic acids `(X)` and `(Y)` cannot be separated by normal methods however when this mixture is treated with optically active quinine give optically acitve salts `(P)` and `(Q)`. These two salts can be separated by fractional crystallization, separated and acidified with `HCl` to from amines and carboxylic acids.
The compound `(X)` and `(Y)` may be
A. `CH_(3)COOH,CH_(3)CH_(2)COOH`
B.
C. `(+)` and `(-)` - Tartaric acid
D. `CH_(3)CH_(2)CH_(2)COOH, CH_(3)CH_(2)CH_(2)CH_(2)COOH`
