What is the role of the team captain?

The role of the team captain primarily revolves around communication and representation on the field, particularly in their interaction with the referee. This aspect of the captain's role is crucial, as it involves conveying the team's needs, expressing concerns, and ensuring the team's understanding of the rules and decisions being made during the match. The captain serves as a liaison between the players and the officiating crew, which aids in maintaining the flow of the game and fostering mutual respect.

Leadership qualities such as exemplifying sportsmanship, motivating teammates, and making strategic decisions also fall under the duties of the captain. While leading warm-up exercises and being involved in substitutions can be beneficial and sometimes fall within the captain's responsibilities, these tasks are not the primary function. Scoring goals is important for all players, but the captain's impact is more significant in terms of leadership and communication during the game. Thus, option B accurately reflects the key responsibilities associated with the team captain's role.
