Final answer:
The baroreceptor reflex is an example of an B) autonomic reflex, which helps maintain vascular homeostasis by regulating heart function in response to changes in blood pressure. Hence, B) is correct.
Step-by-step explanation:
The baroreceptor reflex is an example of an autonomic reflex.
Baroreceptors are specialized stretch receptors located within blood vessels and heart chambers that respond to changes in blood pressure. When blood pressure increases, baroreceptors detect the stretch and send signals to the cardiac centers in the brain, which then regulate heart function to restore blood pressure to normal levels.
This reflex is an automatic response that helps maintain vascular homeostasis by ensuring that blood pressure remains within a certain range.
