If your heart rate increases, it will have an impact on the rate of blood delivery. The heart pumps blood throughout the body, and each time it beats, it pushes out a certain volume of blood. A higher heart rate means that the heart is beating more frequently, which leads to more blood being pumped out of the heart per unit of time. This, in turn, increases the rate at which blood is delivered to various parts of the body. Therefore, the correct response is "Blood delivery rate increases."
