Which of the following statements is true for homogeneous mixtures?

This question was previously asked in
RRB Group D 2025 Question Paper (18-Aug-2026) (Shift 1)
The correct answer is

The particles of a solution are smaller and cannot be seen with the naked eye.

A homogeneous mixture, such as a true solution, has a uniform composition throughout.

Its solute particles are smaller than 1 nm, so they cannot be seen with the naked eye, do not settle on standing and cannot be separated by filtration.

Settling and separation by filtration belong to suspensions, and the Tyndall effect is shown by colloids, both of which are heterogeneous.

Hence, the answer is that the particles of a solution are smaller and cannot be seen with the naked eye.
