Virginia Code § 38.2-1826(C) mandates that licensees (agents, brokers, etc.) report administrative actions—such as license revocation or fines by another state or agency—to the Bureau of Insurance within 30 calendar days of the final disposition. “Final disposition” means the conclusion of the action (e.g., final order or settlement). This requirement ensures Virginia regulators can assess the licensee’s fitness to hold a license and protect consumers. Option C (30 days) matches this statutory timeline precisely. Option A (10 days) is too short and not supported by Virginia law. Option B (20 days) lacks a basis in the Code or study materials. Option D (45 days) exceeds the mandated period, risking delayed oversight. The study guide likely emphasizes this 30-day rule as a critical compliance deadline, reinforced by Virginia’s alignment with NAIC standards for licensee reporting, making C the definitive answer.
