Explanation

The idiom 'bite the bullet' means to face a difficult or unpleasant situation with courage and determination. In the context of the question, Ali has been hesitant but ultimately decides to confront the exam, which embodies this meaning. The incorrect options either suggest giving up (Option A), self-harm (Option C), or avoidance (Option D), all of which do not capture the essence of taking decisive action in the face of difficulty.
