Passage: Let all the experimental rats run for an hour. The first group of rats drank tomato juice an hour before running. The second group drank tomato juice after running. The third group drank tomato juice after running for 30 minutes, and then ran for another 30 minutes after a 1-minute break. The experimental rats in the control group only drank water. Six hours after exercise, the concentration of "TGF- b" in the blood of experimental mice, which is a marker of animal fatigue, was measured. The results showed that compared with the experimental mice that only drank water, the index of the first and third groups of experimental mice decreased by 50% to 60%. While there was almost no difference in the second group of experimental mice.
Question: Which of the followings is the most suitable conclusion for the above experiment?
A. A.Drinking tomato meter can eliminate fatigue caused by exercise
B. B.Drinking tomatoes before exercise can reduce exercise fatigue
C. C.The first three groups of experimental mice ran at the same speed as the experimental mice that only drank water
D. D.In the case of the same exercise intensity and amount of exercise, a long rest in the exercise gap can reduce fatigue
