Why each option matters
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
✓
N:N (many-to-many)
An N:N (many-to-many) relationship allows multiple competitors to be linked to multiple opportunities. Option A (N:1) would allow many opportunities to have one competitor, which is not suitable. Option B (Self-referential relationship) is for hierarchical relationships within the same entity. Option C (1:N) would allow one opportunity to have many competitors, but not the reverse.
