- C. Repolarized
- D. Refractory state
Explanation
The part of a neuron that is already in resting potential is also considered to be in a "polarized" state. Resting potential refers to the electrical state of a neuron when it is at rest and not actively transmitting signals. During this state, there is a separation of charges across the cell membrane, with more negatively charged ions inside the neuron compared to the outside. In a polarized state, the neuron's resting membrane potential is maintained, and there is an electrical potential difference between the inside and outside of the cell. This polarization is a result of the distribution of ions, particularly sodium (Na+) and potassium (K+), across the cell membrane. When a neuron is polarized at its resting potential, it is ready to receive and process incoming signals and can generate an action potential (nerve impulse) if the appropriate stimuli are received.

About Coordination and Control
Coordination depends on receptors, neurons, synapses and nerve impulses, with reflex actions traced through the reflex arc and the roles of major brain regions. Chemical coordination covers endocrine glands and hormones, including how hormones regulate growth, metabolism, reproduction and internal balance, unlike rapid nervous control.
