    The correct option is c. The sensors for the arterial baroreceptor reflex are located in carotid sinus and aortic arch.

    Explanation:

    Baroreceptors are primary sensors (or mechanosensitive nerve endings) that detect distention in vascular walls and are stimulated by mechanical deformations during blood vessel stretching. They are located in the carotid sinus and the aortic arch. The stretching the vessel walls at any of these locations causes vasodilation and bradycardia. The baroreceptors detect the stretching of the vessels due to changes in blood pressure, through them a more efficient control of blood pressure is achieved.
