Answer:
It's A I think
Explanation:
Heart rate will go up as blood isn't getting to the heart as fast possibly because of the veins constricting.
When the blood pressure in the body decreases, then heart rate increases, causing the blood vessels to contract to improve the blood supply. Thus, option A is correct.
What is low blood pressure?
Low blood pressure is the case where the oxygen-rich blood is not supplied accurately to the other organs, including the brain resulting in weakness and dizziness.
The body in the situation of low blood pressure increases the heart rate and narrows the blood vessels (contract) to balance the blood supply to the organs and to reach normal blood pressure.
Therefore, the blood supply is increased by the contraction of the vessels.
