What would happen if the valves separating the chambers and a person's heart did not close?

a) The volume of blood pumped from the atria to the body would be reduced because blood would backflow in the ventisles (WRONG!!!)
b) The volume of blood pump from the ventisles to the body would increase because blood would flow without restriction from the atria
c) The volume of blood pumped from the ventisles to the body would be reduced because blood would backflow into the atria
d) The volume of blood pumped from the atria to the body would increase because blood would flow without restriction from the venticles
