Primate Communication Can Be Compared to Human Communication in That

Primate communication can be compared to human communication in that

A) primate communication is very simple and across all the species consists of only a handful of "meaningful" sounds; this is entirely different from human language.
B) although some primates have the ability to transmit meaning from one individual to another, this always happens within a species, never between species; this is similar to humans, since humans do not really understand other animals either.
C) many primates make sounds that seem to be labels for things, like specific food items or specific predators, but primate communication lacks nuance or complexity of any kind; this is unlike human language.
D) for at least some Old World monkeys and apes, communication seems to be very context dependent, and specific sounds can have different meanings by making small changes; this is like human language.
