Final answer:
A case-control study is more suitable for studying rare diseases because it allows researchers to quickly identify and include a sufficient number of cases with the disease of interest. However, it has limitations such as recall bias and its inability to establish causal relationships.
Step-by-step explanation:
A case-control study is more suitable for studying rare diseases because it allows researchers to quickly identify and include a sufficient number of cases with the disease of interest. By selecting cases with the disease first, researchers can overcome the challenge of low disease prevalence and ensure an adequate sample size. This study design is also cost-effective and less time-consuming compared to cohort studies. However, case-control studies are prone to recall bias and may not establish causal relationships.
