Classification (leader–group): In three pairs, the first term denotes the leader of the second (group/body). One pair instead shows a member and a group. Identify the odd pair.

Introduction / Context:
This problem checks awareness of role–collective relations. Three pairs encode “leader → group led,” while one pair encodes “member → group belonging,” which is categorically different.

Given Data / Assumptions:

• Captain → Team (leader of the team).
• Boss → Gang (leader of a gang).
• Prime Minister → Cabinet (heads/coordinates cabinet decisions in many systems).
• Artist → Troupe (member of the troupe, not its designated leader).

Concept / Approach:
Determine whether the first term is a leader role relative to the second. The pair that expresses “member of” rather than “leader of” is the odd one out.

Step-by-Step Solution:

Verification / Alternative check:
Rephrase as “X leads Y.” The first three read naturally; “Artist leads Troupe” does not necessarily follow.

Why Other Options Are Wrong:

Common Pitfalls:
Assuming a prominent member (artist) automatically implies leadership; leadership is a specific role (e.g., director, leader, or captain).

Final Answer:
Artist-Troupe
