Understand that the problem is asking for the approximate percentage of total body weight that blood constitutes in an average adult.
Recall that blood volume in an average adult is roughly 7-8% of total body weight, which is a commonly accepted physiological value.
Recognize that the other percentages given (1%, 15%, 25%) are either too low or too high compared to standard physiological data.
Confirm that the correct answer aligns with the typical range of 7-8%, which is often rounded to about 8%.
Conclude that blood makes up about 8% of total body weight in an average adult.
