Dora has recently started working on a research study that hypothesizes that people who have a defect in a specific gene may have a predisposition to depression.As a second hypothesis in the study,the researcher is studying the impact of a significant lack of social support in triggering the onset of depression in such people.If Dora's research successfully validates both hypotheses,which of the following conclusion may be drawn?
A)A defect in the gene Dora is studying is directly linked to depression.
B)A lack of social support always leads to clinically significant levels of depression.
C)The defective gene and lack of social support produce a heightened risk of depression.

The research hypothesizes a correlation between a defect in a specific gene and a predisposition to depression, as well as the impact of a lack of social support. If both hypotheses are validated, it can be concluded that the defective gene and lack of social support together heighten the risk of depression. Option A is too definitive and option B is too general. Option D introduces a new concept of polygenic inheritance, which is not mentioned in the hypothesis.
