Discipline, self-control, and responsibility

The governing concept is that discipline in physical education is an internal quality as well as outward obedience. A disciplined learner follows rules, controls emotions, arrives prepared, respects officials and teammates, accepts responsibility for conduct, and continues effort even when supervision is limited. Thus, option C is correct because self-control and responsibility explain why discipline becomes a personal habit rather than mere fear of punishment. Option B is too narrow: listening to commands may be one behaviour, but it does not prove responsible action. Options A and D oppose the cooperative and constructive meaning of discipline.
