I think the answer is b because that makes every one feel better
It looks as though this essay should be an argumentative/persuasive essay. As such, there are two main ways to construct this. Knowing you should refute two points from the article, you could do this by either mentioning the opposing viewpoints first then your refutes (known as the block method), or you could do this point by point by stating an opposing viewpoint, then refuting it in the same paragraph (known as the point-by-point method). That said, here are two sample outlines assuming you mention two points:
OUTLINE 1 (Block Method)
Introduction
Body Paragraph 1
-opposing viewpoint 1
-opposing viewpoint 2
Body Paragraph 2
-your refute of opposing viewpoint 1
-your refute of opposing viewpoint 2
Conclusion
OUTLINE 2 (Point-by-Point)
Introduction
Body Paragraph 1
-opposing viewpoint 1
-your refute of opposing viewpoint 1
Body Paragraph 2
-opposing viewpoint 2
-your refute of opposing viewpoint 2
Conclusion
1 credential
2 certification
3 portfolio
