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