Question

overall, research on the moderate use of caffeine suggests that
a. it may protect against stroke and dementia.
b. it reduces blood pressure.
c. it will increase the likelihood of having a healthy baby.
d. it may result in lung or mouth cancer.

Explanation:

Research indicates moderate caffeine use can have neuro - protective effects, potentially protecting against stroke and dementia. Caffeine typically increases blood pressure, not reduces it. There is no evidence that it increases the likelihood of having a healthy baby, and it is not associated with lung or mouth cancer in moderate amounts.

Answer:

A. it may protect against stroke and dementia.
