An unsuccessful applicant to the state medical college sued the college, claiming that its use of race in admissions violated the Fourteenth Amendment. The district court ruled for the applicant and the state appealed. While the case was on appeal, he graduated. The reviewing court should:
a) Dismiss the case as moot, since the applicant has already graduated
b) Uphold the district court's decision, as it sets a precedent for future cases
c) Remand the case for reconsideration in light of the applicant's graduation
d) Dismiss the case, as the applicant is no longer directly affected
