Which of the following statements are correct?
(A) In ideal solutions, the enthalpy of mixing of the pure components to form the solution is zero.
(B) The volume of the solution is equal to the sum of the volumes of the two components.
(C) In binary ideal solutions, attractive forces between A-A and B-B are nearly equal to those between A-B.
(D) In negative Raoult's law deviation, attractions between A-B are weaker than those of A-A and B-B attractions.
Choose the correct answer from the options given below:

Apply the relevant identity from the chapter and substitute the values established in the previous step, keeping the original constraint in view.

Use the simplified expression to isolate the unknown, then plug the result back into the question setup to confirm the working is internally consistent.

Cross-check against a boundary or limiting case. Both the dimensional balance and the qualitative behaviour at the extreme should agree with the candidate answer.

Combine the steps above to identify the correct option. The remaining choices each fail at least one of the consistency, dimensional, or boundary checks.
