B.
28. Correct

D.
25.
The answer is "28."
You must answer 28 of the 35 questions correctly to pass the Class C knowledge test: 80%. Missing 7 questions is the maximum that still allows you to pass; the eighth wrong answer is the failure threshold. Recalling a roughly 70% pass mark from other tests sends readers to D, but Oregon sets the bar at 28/35, not a lower count.
The traps in the wrong answers
A. 32.
32 exceeds the minimum; 28 is the threshold. This answer inflates the requirement to roughly 90%; the manual states 28 correct is enough to pass.
C. 20.
20/35 is below the passing threshold. This answer confuses the passing score with a much lower bar; the manual sets 28, not 20.
D. 25.
25/35 is below the passing threshold of 28. This answer reaches for a roughly 70% pass mark; Oregon requires 28/35, not a lower count.
