If plant height is measured which type of variable is it?

Answer and explanation

Correct answer: Dependent variable

A dependent variable is the result that is measured in an experiment. Its value may change in response to the independent variable. In a plant investigation, the researcher might change water amount, light, or fertilizer, and then measure plant height to see what effect the chosen condition has. The dependent variable must be recorded using a clear and consistent method.

Option D is correct because plant height is the measured outcome. It depends on the experimental conditions and may increase differently when the independent variable changes. A controlled variable is deliberately kept the same, an independent variable is deliberately changed, and a constant refers to something that remains unchanged. The key clue is the word “measured”: the measured response is the dependent variable.
