A

The reference ranges for PSA levels vary by age: for men under 50, it's typically <2.5 ng/mL; for ages 50–59, <3.5 ng/mL; for ages 60–69, <4.5 ng/mL; and for those 70 and older, <6.5 ng/mL. These ranges help in assessing whether further evaluation is necessary.

This is one answer. The complete system — the psychology, the biology, and the method — is in the book.
