Final answer:
The correct answer to the question regarding a group of people working together, particularly in sports, is 'Team'. This term represents a collective group united by a common goal, distinct from other group terms such as choir, band, or committee.
Step-by-step explanation:
A group of people working together, especially in a sport, is generally referred to as a team. This collective noun signifies a collection of individuals who interact frequently and share a sense of aligned identity with the common goal of achieving success in their sport or area of teamwork. A team is often associated with characteristics such as cooperation, coordination, and collective effort towards a common objective, whether it is in a professional setting or within sporting activities.
Collective nouns are used to refer to a group acting as a single entity, like a choir, band, or committee. However, when it comes to sports or collaborations that require teamwork, the appropriate term is 'team'. Similarly, committee refers to a group of people officially delegated to perform a function, such as investigating or reporting on a matter.
In conclusion, the answer to the student's question is: b) Team. This term accurately encapsulates the concept of a group of people joining forces with a shared aim, particularly within the realm of sports or other group activities requiring unity and team effort.
