Answer & Solution

Correct Answer

(D) True solution is a heterogenous mixture of two or more substances with fixed composition.

Step-by-step Solution

Detailed explanation

A true solution is a homogeneous mixture with consistent properties. Filtration cannot separate the solute from the solution in a true solution. The solute's particle size is around the same as the solvent's, and the solvent and solute move through the filter paper together.
A true solution is a homogeneous mixture of two or more substances in which the particle size of the material dissolved (solute) in the solvent is less than \(10-9 \mathrm{~m}\) or \(1 \mathrm{~nm}\). True solution is exemplified by a simple sugar solution in water.

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.
