Solution

The correct option is A 5 litre
The blood travels around the body and back to the heart in about one minute if the person is at rest. The heart beats 70 times a minute, with each beat the heart pumps 60 to 90 mililiters (2 to 3 ounces) of blood out of the heart. It can move 5 liters of blood in one minute and 7600 liters (2000 gallons) per day. So, the correct option is "A" (5 Litre).
