The hypothesis is specifically about context-dependent learning, i.e. the idea that the learning context (in this case, the presence of high doses of caffeine) affects memory recall. Therefore, option D is the only one that directly addresses this idea by testing whether drinking coffee during both the learning and testing phases leads to better memory recall than just drinking coffee during the learning phase. Options A and B are too general and do not explicitly test context-dependent learning. Option C is correlational and only shows an association between coffee consumption and memory performance, but does not test the hypothesis that caffeine specifically affects context-dependent learning.
