A longitudinal design involves collecting data from the same participants at multiple points in time, allowing researchers to examine patterns of change and stability in the variables of interest. In contrast, a cross-sectional design involves collecting data from different groups of participants at a single point in time, and a latitudinal design is not a recognized research method. Short-term designs may involve repeated measures over a brief period of time, but would not qualify as a longitudinal design. Therefore, the best choice is B, longitudinal.
