Answer:
B: No, this is an observational study and we cannot conclude causation
Explanation:
Observational study: In psychological research, the term observational study is defined as a non-experimental yet an empirical investigation lead by the researchers related to the effects being caused by a specific treatment.
An observational study is one of the types of correlational studies in which an experimenter or researcher tends to observe the behaviour of the subjects or participants.
An observational study does not prove or conclude causation because correlational studies can only determine the relationship between two different variables but can not prove or show causation which is being done by experimental studies.
