Lack's hypothesis on optimal clutch size.
The peak in the curve indicates that natural selection favors:
- A
The smallest possible clutch
- B
Random clutch sizes
- C
The largest possible clutch
- Dcheck_circle
A clutch size that maximizes the number of surviving offspring
Explanation
Lack predicted an intermediate clutch size that maximizes the number of offspring surviving to fledge, balancing per-offspring care with brood size.
