c. primates tend to have large brains in relation to their body size
d. primates usually give birth to one offspring at a time.

b. All primates rely more on vision and less on their sense of smell.

Explanation:

Primates make up a group of vertebrate animals and include apes (monkeys), lemurs and humans. All these beings have many similarities to each other, for example, all primates usually have five digits on each hand and foot, primates tend to have large brains in relation to body size and the larger the smarter brain the primate is, primates usually give birth one baby at a time. Not all primates rely more on sight and less on smell; humans tend to rely on sight more than on smell, but most other primates have more developed than humans, so the smell is more important to them.
