Answer:

The answer is B. Subjects in the study are all the same age.

Explanation:

A longitudinal study is an observational study where the observation of the samples or individuals is continuous to follow a particular pattern over a prolonged period of time.

For examples, studies of the behaviour of twins or studies observing the effects of videogames in teenagers.

Therefore, subjects in the study are all the same age or group age.
