Optimal foraging theory (OFT) holds that animals' foraging behaviors reflect cost-benefit trade-offs that vary by species and with dynamic ecological circumstances. One such circumstance is lunar intensity, which Rodrigo A. Vásquez found to be negatively associated with foraging by olive grass mice but Deborah J. Curtis and colleagues found to be positively associated with foraging by mongoose lemurs. This discrepancy is explicable in terms of OFT: the lemurs' greater reliance on vision means that higher lunar intensity benefits them more than it benefits the mice.
Information in the text best supports which statement about OFT?
It tends to allow for a better understanding of the benefits of ecological circumstances than the costs of those circumstances.
A
It can account for observations of different species responding differently to similar ecological circumstances.
B
It can explain why some species act in accordance with cost-benefit trade-offs and others do not.
C
It may be weakened by the finding that the costs and benefits associated with a particular ecological circumstance vary by species.
D
