Explanation:

To determine the study design, we analyze each option:

• Cross - sectional: Studies different groups at one time point, not over time. Eliminate.
• Experimental: Involves manipulating variables, which isn't done here. Eliminate.
• Longitudinal: Follows the same group over time to observe changes (here, following preschoolers over time to predict later schizophrenia development). This matches.
• Survey: Collects data via questionnaires/interviews, not long - term follow - up. Eliminate.

Answer:

C. longitudinal
