Answer:
Option D
Explanation:
Conditions that are correct for real solutions showing negative deviation from Raoult's law are as follows
$P_{A} < P_{A} ^{0} X_{A} $ and $P_{B} <P_{A} ^{0} X_{B}$
$\triangle _{mix} H=-ve$
Dissolution is exothermic heating decreases solubility $\triangle_{mixing} V=-ve$
