The correct answer is B. It gives specific examples of ways the author can improve the paper.
Explanation:
Feedback, which is part of the peer-review process consists of evaluating and creating a critique about a work such as a text or presentation of a peer, which can be a classmate or colleague. However, for a peer-review to be both positive and effective, the person that is providing the feedback should first analyze carefully the work to be evaluated, acknowledge the positive aspects of the work and then point out those that need to be improved including recommendations on the way to making the work better. This is recommended because the main purpose is to help the other to improve rather than just criticizing the work. Considering this, the statement that is an example of helpful feedback is "it gives specific examples of ways the author can improve the paper".
