In a longitudinal research design, the same group of participants is tested repeatedly. In this type of research there is one record per individual.
In a longitudinal design, different age groups are tested at the same time.

Correct answer is:

A. Longitudinal; Cross-sectional.

Explanation:

Longitudinal research design:

A longitudinal study is an observational analysis system in which data is collected for the identical subjects frequently across a span of time. Longitudinal analysis designs can elongate over years or indeed decades. In a longitudinal group research, the identical people are examined across the research period.

Cross-sectional research design:

In the pharmaceutical analysis and political science, a cross-sectional research (also identified as a cross-sectional investigation, intersecting research, prevalence research) is a kind of observational research that examines data from a population, or a characteristic subset, at a particular duration in time—that is, cross-sectional data.
