The Graduate Management Admissions Council Announced That It Was Canceling

The Graduate Management Admissions Council announced that it was canceling the GMAT scores of 84 applicants and students.  The Council found that the students were active users of a now shut-down website, Scoretop.com, a site with origins in China that posted live questions from the GMAT.  The site had 5,000 to 6,000 subscribers who paid $30 per month for access, but the Council is only canceling the scores of those against whom it feels it has an airtight case.  Two of the students whose scores were canceled are currently enrolled at the University of Chicago's MBA program and another has already graduated from Stanford's MBA program. Twelve of the students whose scores were canceled had posted questions on Scoretop.com and the remaining 72 allowed the site to post their testimonials that they had seen the Scoretop.com questions on their GMAT.  Ten of the 72 students had applied to Stanford but were denied admission.  Which ethical category does the conduct of the students who posted live questions fit into?

A) Taking something that does not belong to you
B) Balancing ethical dilemmas
C) Interpersonal abuse
D) Organizational abuse
