what areas of the body do spinal nerves innervate?

lower limbs
trunk
head
upper limbs

Explanation:

Spinal nerves (except for the cervical nerves that contribute to the plexuses for the head - but the head is mainly innervated by cranial nerves) innervate the trunk, upper limbs (via brachial plexus from spinal nerves), and lower limbs (via lumbosacral plexus from spinal nerves). The head is mostly innervated by cranial nerves, so "Head" is not correct.

Answer:

A. Lower limbs, B. Trunk, D. Upper limbs
