According to Standard VII(B), a person is considered a candidate in the CFA Program if they meet one of the following criteria:

1. Their registration application has been accepted by CFA Institute, and they are enrolled to sit for a specified examination.
2. They have already sat for a specified examination but have not yet received the results.

• Option A is incorrect because the individual has not yet registered for the Level III exam, so they do not meet the criteria.
• Option B is incorrect because the individual has not registered for the next exam administration, so they do not qualify as a candidate.
• Option C is correct because the individual has sat for the Level III exam and is awaiting results, fulfilling the second criterion of Standard VII(B).
