C Correct answer
Explanation

The myelin sheath is a fatty layer that wraps around axons, providing electrical insulation and protection. Nodes of Ranvier are gaps in the myelin sheath, synapses are junctions between neurons, and axon terminals transmit signals to other cells - none of these insulate and protect the axon.
