Answer 1

The correct option is B

Mixed nerve

A mixed nerve carries impulses to and from the brain and spinal cord. It is a type of nerve that is formed from a combination of sensory nerve fibres and motor nerve fibres. Sensory nerve carries impulses from various parts of the body to the brain and the spinal cord whereas motor nerves carry impulses from the brain and spinal cord to various parts of the body. Connective tissues are structures that cover a group of nerve fibres.
