Correct Answer: Sympathetic nerves
Solution : The correct option is Sympathetic nerves.
The sympathetic nervous system, specifically the cardiac accelerator nerve, increases the rate of heartbeats. This nerve releases norepinephrine, which binds to receptors on the heart's cells and leads to an increase in heart rate, and force of contraction, preparing the body for a "fight or flight" response.
