Use the hypothetical or idealized survivorship curves in the figure to answer the following question. Which statement best explains survivorship curve B?
A) It is likely a species that provides little postnatal care, but lots of care for offspring during midlife as indicated by increased survivorship.
B) This curve is likely for a species that produces lots of offspring, only a few of which are expected to survive.
C) It is likely a species where no individuals in the cohort die when they are at 60-70% relative age.
D) Survivorship can only decrease; therefore, this curve could not happen in nature.
