Consider the following statements about the solutions formed by mixing two liquids.

A. An ideal solution thus formed obeys Raoult's law throughout the composition range.

B. Mixture of chloroform and acetone shows negative deviation from Raoult's law.

C. Mixture of aniline and phenol shows positive deviation from Raoult's law

Assertion A: For an ideal solution formed by mixing liquids $\mathbf{P}$ and $\mathbf{Q}, \Delta_{\text {mix }} H=0$ and $\Delta_{\text {mix }} V=0$

Reason R: No interactions occur between P and Q

In the light of the above statements, choose the most appropriate answer from the options given below.

Identify the correct statements :

(A) The molality of 2.5 g of ethanoic acid (Molar mass : $60 \mathrm{~g} \mathrm{~mol}^{-1}$ ) in 75 g of benzene solution is 0.556 m .

(B) The molarity of a solution containing 5 g of NaOH (molar mass : $40 \mathrm{~g} \mathrm{~mol}^{-1}$ ) in 450 mL of solution is 0.278 M at 298 K .

(C) Aquatic species are more comfortable in cold water.

(D) The solubility of gas increases with decrease in pressure.

(E) For a binary mixture of $A$ and $B$, the number of moles of $A$ and $B$ are $n_A$ and $n_B$ respectively. The mole fraction of $B$ will be $x_B=\frac{n_A}{n_A+n_B}$.
