QuestionChoice
This is incorrect because it is untrue. In fact, cross-sectional, cohort and case-control studies are not suitable for studying rarer diseases or exposures. This is because even in large samples, there may still be no one with the disease.

e
Not suitable for common diseases
QuestionChoice
This is a disadvantage mainly associated with case-control studies. Here, groups are defined by the presence or absence of disease, so only one condition can be studied at a time. This is not an issue in cross-sectional studies as data from multiple diseases can be collected simultaneously.

c
Only a single disease can be studied at a time
QuestionChoice
This is a disadvantage mainly associated with cross-sectional studies. They are descriptive in nature and cannot show causal relationships.

a
Limited potential to establish disease aetiology
QuestionChoice
This is an advantage of cross-sectional studies. Since data only needs to be collected at a single point in time, they are less time-consuming than other study design methods.

b
Relatively fast and inexpensive
QuestionChoice
This is a disadvantage mainly associated with cohort studies. They may require long periods of follow-up as it may take a long time after exposure for the disease to occur. This is not an issue in cross-sectional studies as data is only collected at a single point in time.
