Answer:
The correct answer is an opposable thumb, large and well developed brain, and binocular vision.
Explanation:
A primate refers to a member of the mammalian order Primates that constitute two suborders, that is, the anthropoids (apes, monkeys, and human beings) and the prosimians (lorises, lemurs, and tarsiers).
The behavioral and anatomical characteristics, which differentiate primates from other mammalian orders comprise an absence of strong specialization in composition, that is, prehensile feet and hands, generally with great toes and opposable thumbs.
Apart from this, the primates comprise flattened nails in place of claws, acute vision with binocular vision, and comparatively bigger brain demonstrating the extent of cortical folding.
