Having compassion in sports includes all of the following except: a. refraining from showing off b. embarrassing less skilled players c. respecting other players d. injured players

B. embarrassing less skilled players

Explanation:

Modern psychology defines compassion as "the feeling that arises when one witnesses the uneasiness (suffering, stress) of the other (or one's own), and which generates the motivation or desire to help (or to take care of oneself"). Based on this, we can say that compassion is a feeling of helping people, not of humiliating or harming them. In sport is no different, so we can conclude that among the options given in the question above, one that does not represent an example of compassion in sport is the letter B, as these options show a situation of embarrassment and humiliation.

b) the heart is a pump made of muscle and that is difficult to grow in the lab.
