Answer:
(B)
I might not give a lot of credibility to the study because of possible "generalizability" limitations.
Step-by-step explanation:
Generalizability is the extent to which the findings from an experiment in a particular setting can be applied to a different setting.
According to generalizability theory, the larger a sample population is, the more results from an experiment using that sample can be generalized.
Therefore a study that obtained its sample only from Caucasian subjects from Seattle, could have "generalizability" limitations.
