BThe impact of the observer on the participant

CA clear cause-and-effect relationship

DThe relationship between two events or variables ✓ Correct

Correct answer: (D) The relationship between two events or variables

Explanation

A correlational study determines the relationship between two events or variables.

The impact of one manipulated cause on an effect belongs to experiments.

The impact of the observer on the participant is a reactivity concern, not this.

A clear cause-and-effect relationship needs manipulation and control, absent here.

Correlation reports direction and strength but not causation.

A third variable may explain any observed correlation.
