Within how many days must a licensee notify the NC Commission of address change?

Option B (14 days) is incorrect because it exceeds the mandatory timeframe specified in Rule 21. This option may tempt students who confuse it with other regulatory periods or misremember the specific requirement.

Option C (21 days) is incorrect as it's double the required timeframe. Students might select this option if they're thinking of quarterly reporting periods or other administrative timelines not related to address changes.

Option D (30 days) is incorrect because it's triple the required notification period. This option may attract students who are thinking of license renewal deadlines or other monthly reporting requirements.
