B.
12 of 18
-
C.
14 of 18

D.
16 of 18
The answer is "15 of 18"
The Knowledge Test contains 18 multiple choice questions, and the manual sets the passing score at 15 correct. Drivers who reach for a generic two-thirds pass mark rather than the printed cutoff land on B.
The traps in the wrong answers
B. 12 of 18
The passing score is 15 of 18, not 12. This answer applies a generic two-thirds passing rule instead of the manual's printed 15-of-18 threshold.
C. 14 of 18
The passing score is 15 of 18, not 14. The manual gives an exact cutoff, not a rounded percentage. This answer anchors on a rough 80-percent passing rule of thumb and rounds down to 14 instead of using the manual's exact 15-question count.
D. 16 of 18
The passing score is 15 of 18, not 16. This answer confuses Pennsylvania's 15-of-18 threshold with the tougher passing counts used on the Commercial Driver's Manual tests.
