    A. longer pregnancies & periods of infant dependency

    Explanation:

    Primates are known to mature slowly compared to other mammals, they have a longer gestation period and longer period of infant dependency. Therefore the period between birth and adulthood is usually longer compared to other mammals, which then result to late age in their first reproduction.

    For example humans have a gestation period of 365 days while baboons is 187 days compared to rabbits with a gestation period of about 33 days or mice with a gestation period of about 20 days

    Of any primate, humans exhibit the longest period of infant dependency, Chimpanzee is about 5 years compared to other mammals.
