Final answer:
The Insurance Commissioner can examine the records of an insurer anytime without notice to ensure they are operating in a sound manner and protecting the interests of policyholders.
Step-by-step explanation:
When it comes to the power of the Insurance Commissioner to examine the records of an insurer, the correct answer is B. Anytime without notice. The Insurance Commissioner is typically empowered by state law to regulate the insurance industry and ensure compliance with all applicable laws and regulations. As part of this regulatory oversight, the Commissioner has the authority to conduct examinations of insurers' records to ensure that they are operating in a sound manner and protecting the interests of policyholders. This authority allows the Commissioner to perform such examinations without the need for permission from the insurer, a lawsuit, or any advance notice, though they might often do so during regular business hours as a matter of practicality.
