Which plant will be the control group in an investigation of fertiliser effect?

Answer and explanation

Correct answer: Plant without fertiliser

Direct answer: A, the plant without fertiliser. A control group provides a baseline for comparison and does not receive the treatment being tested. Step by step: keep plant type, water, light, soil, and other conditions as similar as possible; give fertiliser to the experimental group; give none to the control group; compare growth. A shows what happens without the fertiliser. B receives extra treatment, so it is experimental. C and D are selected by outcomes, not by experimental conditions, and choosing them can create bias. Memory cue: control means no tested treatment.
