Answer: (C)

Verified step by step guidance

1. Understand that the total blood volume in a typical healthy adult human is generally measured in pints or liters and depends on factors such as body size and sex.
2. Recall that an average adult has about 4.5 to 6 liters of blood circulating in their body.
3. Convert liters to pints, knowing that 1 liter is approximately equal to 2.11 pints.
4. Multiply the average blood volume in liters by the conversion factor to get the volume in pints: \(\text{Blood volume (pints)} = \text{Blood volume (liters)} \times 2.11\).
5. Compare the calculated range of pints to the given options to identify the correct range, which is typically around 8 to 10 pints for a healthy adult.
