    A. changes in arterial pressure

    Explanation:

    Baroreceptors are located in the aortic arch and carotid arteries. Baroreceptors are the sensory receptors that sense the stretching of arteries as a result of the pressure of the blood flowing through them.

    For example, the stretch of the wall of the carotid sinus caused by the pressure of the blood in carotid arteries is sensed by baroreceptors present in the wall of carotid sinuses.
