Brief Explanations:
A concluding statement for an article - evaluation should summarize the overall assessment. The last option evaluates the author's claim and its support, which is appropriate for a conclusion. The first option just praises an aspect of explanation, the second gives a reason for recycling not related to article - evaluation, and the third is a statement from the article rather than an evaluation.
