Which Statement About David Lack's Study on Geographic Variation in Clutch

Question

Which statement about David Lack's study on geographic variation in clutch size in birds is true?
A) Lack's analysis led to experiments supporting the hypothesis that there is a trade-off between egg number and offspring survivorship.
B) Lack's results stimulated the development of Charnov's dimensionless ratio c for comparing maturation rates of different species.
C) Lack found that clutch size for birds tends to be higher closer to the equator, where more food is available.
D) On a global scale, Lack found a strong longitudinal trend in clutch size.

Accepted Answer

Lack's analysis suggested that there is a trade-off between the number of eggs laid and the survivorship of the offspring, which was later supported by experiments.
