Understand that the question asks for the approximate volume of blood in a typical healthy adult's body, measured in quarts.
Recall that the average adult human body contains about 4.5 to 5.5 liters of blood, depending on factors like size and sex.
Convert liters to quarts, knowing that 1 liter is approximately equal to 1.057 quarts.
Multiply the average blood volume in liters by the conversion factor to get the volume in quarts: \(\text{Blood volume (quarts)} = \text{Blood volume (liters)} \times 1.057\).
Compare the calculated approximate value to the given options to identify the closest match, which is about 5 quarts.
