The best answer choice for the question: Which of the following best describes the results of Dr. Sneed´s study on volunteering and hypertension, would be, D: The risk of hypertension is lower only for people who volunteer more than 200 hours per year.

Explanation:

The study, which was carried out by Rodlescia S. Sneed and Sheldon Cohen, and which was published under the name "A Prospective Study of Volunteerism and Hypertension Risk in Older Adults" was a very interesting one where the correlation between the risk of developing hypertension in older adults, and the hours spent at volunteering activities, 200 or more in a year, regardless of age, sex, origin, race, and other factors, was studied. In the end, the results of this study show that there is, in fact, a relation between the two things and it is believed that the reason is that volunteering in older adults brings positive concepts about self, and others, that affect the body positively. Thus, although volunteering won´t change a person´s hypertensive state and it is not a cure either, it does reduce the incidence of hypertension on the people that were followed for 4 years. The clarification, however, made by the investigators, is that this applies to older adults who volunteered at least 200 hours or more, and not the other group studied, which was the one that volunteered less that 200 and to a minimum of 100 hours per year. This is why the answer is D.
