Answer: A) Individuals of different ages are being compared to one another

Explanation: Cross sectional design or study, which is also known as transverse research study is a type of observational study which analyses data from a group of people who are different in the variable of interest but share other similar characteristics.

For example, the socioeconomic status of a particular population can be studied using age as the variable of interest. The disadvantage lies in the fact that certain age groups are favoured in each clime and the level of exposure, knowledge and experience may vary widely between a population of differing age groups.
