The correct option is D Patriotism
The idea of patriotism has come to be inextricably linked with sports, both at the level of individual competition as well as team-based events. National teams, for instance, are backed by entire populations as a result. Eg. The Indian cricket team that enjoys immense support across the country.
Individual competitors representing their country at events such as the Olympics are also examples of how sports and patriotism can go hand-in-hand.
