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

Dispersed phase and dispersion medium

A colloid is a heterogeneous mixture in which particles of one substance are spread through another.

The spread-out particles form the dispersed phase, and the substance in which they are spread is the dispersion medium; for example, in milk fat droplets are dispersed in water.

Solute and solvent are the terms used for true solutions.

Hence, the answer is dispersed phase and dispersion medium.
