The correct answer is C) "As a college student, I am opposed to tuition being raised."
The quote that reveals the author's point of view and potential for bias is "As a college student, I am opposed to tuition being raised."
This statement is potentially biased because the author is expressing its own point of view due to its personal experience, background, and interests. The author is seeing the issue from its side. Probably, a school professor would have another perspective, the Principal of the school too, and the major of the city as a government representant, another.
