Correct answer: (C) Placebo group

Explanation

A placebo group receives an inert treatment that appears real but has no active effect.

The experimental group receives the actual treatment being tested.

A control group receives no treatment and provides a baseline for comparison.

Non-dependent group is not a recognised research term.

Placebo controls isolate the psychological effect of merely receiving a treatment.

Double blind designs keep both participants and researchers unaware of group assignment.
