Answer:

a) longitudinal

Explanation:

  • Studies can be observational (when no intervention happens) or experimental (when a variable is manipulated, an experiment is conducted).
  • Observational studies, based on time, are classified as longitudinal or cross-sectional.
  1. Longitudinal studies follow the same group of people during a determined period of time.
  2. Cross-sectional studies are defined as "snap shots", they compare different groups of people at one specific moment of time.
