Longitudinal research can take years or even decades to complete. During this time, the historical context may change in ways that can affect the results. For example, social, political, or economic factors may change that could influence the behavior of the participants. This makes it important to consider the changing context and its potential impact on the study findings. A is not a problem as aging is often the focus of longitudinal research. B may be a challenge, but it is not a problem as many longitudinal studies recruit new participants over time. D is not a problem with longitudinal research itself, but rather with the specific behavior being studied.
