During blood circulation, the heart muscle contracts and the impure blood passes through the heart and lungs, then purified blood flows through a sequential process of:
A. Blood passes into left ventricle
B. Discharges blood into various arteries and capillaries
C. Blood finds its way into left atrium
D. Blood passes into right ventricle
E. Blood finds its way into lungs

• A. (D), (A), (C), (B), (E)
• B. (D), (A), (B), (C), (E)
• C. (D), (C), (B), (A), (E)
