To determine when a cause-and-effect conclusion about the relationship between two variables in an experiment has been reached, the most relevant element from your list would be **"random selection of participants."**
Random selection helps to eliminate bias and ensures that the sample is representative of the larger population, which is crucial for establishing a causal relationship. While factors like study design also play a role, random selection is essential for supporting strong causal inferences in experimental research.
