Answer #1

12. E. Have something in common at the baseline and are followed over time to assess their outcomes

EXPLANATION:

In Cohort study, participants have something in common at the baseline and are followed over time to assess their outcomes. Therefore, E stand correct.

In Cohort study, participants do not have any outcome of interest. So, A and C options stand incorrect. Some of the participants may dontd have the exposure at the time of initiation of study. So B option is incorrect. It's not always a random sample of a defined population. So D is incorrect.
