When an artery gets a constricted region due to plaque, how does the pressure in this region compare to the pressure in an unconstricted region adjacent?

a. Since this is a closed system, the pressure is the same in both regions. b. In the constricted region the blood moves at a higher speed than in the unconstricted region resulting in an increased pressure. c. In the constricted region the blood moves at a higher speed than in the unconstricted region resulting in a decreased pressure. d. In the constricted region the blood moves at a lower speed than in the unconstricted region resulting in an increased pressure.
