Which statement best describes the relationship between dominance rank and reproductive success (RS) among primate females?
A) High rank may occasionally be correlated with high RS in the short-term, but (except possibly for chimpanzees) the lifetime effects of rank on reproduction are unknown.
B) No association between dominance rank and RS, in either the short-term or the long-term, have been reported for primate females except for chimpanzee females.
C) Strong rank differences are not characteristic of primate females and, in most species, all adult females have roughly similar levels of RS.
D) There is a positive lifetime correlation between these variables. Females born low-ranking will have few offspring; females born high-ranking will produce many.
E) none of the above
