Question 16
The chart shows the responses of all Secondary 1 students at Integrity Secondary School to a multiple-choice question. Horizontal grid lines are equally spaced. A correct response scores 2 points, no response 0, and a wrong response −1. The total is −120 points. If B is correct, how many students answered correctly? These scoring rules are part of this word problem, independent of platform exam scoring.

Chart label: “No response” means no answer.
Answer format: enter one whole number without units. The printed paper uses four answer-sheet digits with leading zeros when needed; ordinary numeric entry is used here.
