    • Myelinated

    • Unmyelinated

    • Your mom

    Correct Answer
    A. Myelinated
    Explanation
    Myelinated neurons conduct faster than unmyelinated neurons because myelination is the process of insulating the axon with a fatty substance called myelin. This insulation allows electrical signals to be transmitted more efficiently along the axon, resulting in faster conduction of nerve impulses. Unmyelinated neurons lack this insulation, so the transmission of signals is slower.
