Answer: (B)

Verified step by step guidance

1. Understand that the question asks for the typical volume of blood in an average adult human body, which is a factual knowledge-based question rather than a calculation problem.
2. Recall that the average adult human body contains a certain volume of blood that circulates through the cardiovascular system, supplying oxygen and nutrients to tissues.
3. Remember that blood volume is often measured in liters or quarts, and the average adult has roughly 4.5 to 5.5 liters of blood.
4. Convert liters to quarts if necessary, knowing that 1 liter is approximately 1.06 quarts, so 5 liters is about 5 quarts.
5. Conclude that the typical blood volume in an average adult is about 5 quarts, which matches the correct answer choice.
