The researchers hypothesize that folate and B6 hinders the development of heart disease in women. This is based on a phenomenon shown in a recent study of female physicians: the more folate and B6 they had in their diet, the less likely they were to develop heart disease (and vice versa).

The researchers assume that it is the folate and B6 in the female physicians’ diets that are preventing them from developing heart disease, as opposed to some other factor(s) in their diets or lifestyles.

This weakens the researchers’ conclusion. It attacks their assumption that the B6 and folate are the critical factors that inhibit heart disease in the female physicians, as opposed to some other factor—in this case, significant amounts of nonvitamin nutrients.

This does not affect the argument. It may be that the researchers’ hypothesis is very unlikely, but that alone doesn’t make it any less convincing.

This does not affect the argument. While physicians’ knowledge about how diet impacts health may influence their dietary choices, it should not affect how the vitamins in their diet influence their health, which is what the study is about.

This does not affect the argument. (D) does not offer reason to suspect that physicians with preexisting heart conditions confounded the study’s results—we would have to assume that they also didn’t eat a lot of B6 and folate for there to be any potential weakening effect.

This does not affect the argument. The amount of folate and B6 in most foods can be minimal without weakening the researcher’s hypothesis that they still have the effect of inhibiting the development of heart disease.
