Solution

The correct option is C Assertion is correct but Reason is incorrect.
The human brain is larger than other animals hence we can say that the brain is the hallmark of the man and the measurement of it must be the key to the understanding of his unique intellectual properties. The man is more intelligent and advanced than the primates because of large cranial capacity than others.
The lumbar curve is present in man which is responsible for the erect posture. Lumbar curve is absent in the vertebral column of the apes.
