External validity is concerned with the extent to which research results can be generalized to the real world. It deals with the issue of whether or not the findings from an experiment can be projected to other settings and situations beyond the experimental context. Option A refers to construct validity, which is concerned with the extent to which a measure or treatment accurately reflects the concept it is intended to measure. Option B does not accurately reflect the concept of external validity, as a mock-up store may not be representative of a real store setting. Option D is incorrect as only option C accurately describes the concept of external validity.
