Passage: Eighty-six patients with T-type disease received the same treatment. In one study, they were equally divided into two groups, with all members of one group participating in collectively encouraging activities once a week, while the other group did not. Ten years later, 41 patients died in each group. It is clear that collectively encouraging activities does not make people with T-type disease live longer.
Question: Which of the following options, if true, would most strongly weaken the above argument?
A. A.For patients who were still alive 10 years later, the two who took part in the collectively encouraging activities lived longer than the two who did not.
B. B.The members of the group who took part in the collectively encouraging activities once a week lived an average of two years longer than the other group.
C. C.Some doctors believe that participating in the collectively encouraging activities once a week will reduce the confidence of patients receiving treatment.
D. D.Patients who participate in the collectively encouraging activities once a week report that such activities can help them fight the disease.
