The correct answer is C because the CMMC ecosystem treats conflicts of interest as both actual and perceived conflicts. The CMMC Code of Professional Conduct requires CMMC ecosystem members to avoid participating in any activity, practice, or transaction that could result in an actual or perceived conflict of interest. It also requires compliance with conflict-of-interest prohibitions and restricts CMMC ecosystem members from participating in a Level 2 certification process where their prior role or relationship could compromise objectivity.

A conflict of interest exists when professional judgment, independence, or impartiality could be affected, or reasonably appear to be affected, by another interest, relationship, duty, or prior activity. In CMMC, this is especially important because assessment credibility depends on independence between consulting and certification assessment functions. For example, an assessor or C3PAO that previously helped design, implement, or remediate the OSC’s cybersecurity program may have an actual or perceived conflict when later assessing that same OSC. Option A is incorrect because lack of transparency may contribute to a conflict issue, but it is not the definition. Option B is too broad because not every legal violation is a conflict of interest. Option D describes a disclosure problem, not a conflict of interest. Therefore, the best answer is C , a perceived or actual conflict.
