Answer 1

The strongest evidence to support the claim that "Drinking coffee is good for your health" is:

B. In one study, those who reported drinking more than six or seven cups of coffee daily were thirty-five percent less likely to have type 2 diabetes than those who drank fewer than two cups daily.
