Final answer:
Low resting heart rates in healthy individuals, such as athletes, have been found not to correlate with criminal behavior. Current research does not support linking low heart rates to a predisposition for criminal activities.
Step-by-step explanation:
Regarding the group of teenagers with low resting heart rates discovered during medical check-ups at a high school, if these rates are a result of them being trained athletes or otherwise healthy without exhibiting symptoms such as weakness or fatigue, there is no indication that such physiological measures have a correlation with criminal tendencies. Therefore, the most likely answer to the statement in question would be that their heart rates have no correlation with criminal activities (C).
It's important to note that while some research suggests a potential link between certain behaviors like the Type A behavior pattern and heart disease, this does not translate into a direct association between heart rate and likelihood of engaging in criminal behavior. The assertion that a low resting heart rate predicts future crime involvement is unsupported by the established research presented.
