Answer 1

D. cross-sectional design

Step-by-step explanation:

Cross-sectional design: In psychology, the term cross-sectional research design is defined as an observational type of research design. A researcher while conducting a cross-sectional research design investigates the exposure and the outcome in the research participants simultaneously. The cross-sectional research design is considered as purely descriptive.

Example: A researcher uses different age-group people for researching the prevalence of cancer in a particular population who smokes.

In the question above, Professor Grant is using a cross-sectional research design.
