What defines a club interdependence system in sport leagues?

• A. A league where all teams play in a single division with no movement between levels.
• B. A system where teams in different levels are connected through promotion and relegation, allowing movement based on performance.
• C. A model where only wealthier clubs can ascend to higher leagues through auctions.
• D. A system where teams are independent and never replace top teams.

Answer: (B)

Interdependence in a club league system comes from the way different levels are tied together through promotion and relegation. In this setup, performance on the field directly affects which division a club plays in next season. A team that excels in its current level earns promotion to a higher division, while poorer performance leads to relegation to a lower one. That creates a dynamic pyramid where the makeup of the top leagues depends on outcomes across the entire system, and financial and competitive pressures can cascade up or down based on results.

This is why it’s the best description: it captures the connected, performance-driven movement between levels that defines a club interdependence system. The other models don’t fit because a rigid single-division league eliminates cross-level dependence; an auction-based ascent relies on money rather than results; and a system where teams are independent and never replace top teams lacks any ongoing interaction between levels.
