Final answer:
The Commissioner must give a person at least 15 days' advance notice of an unfair trade practice hearing. Option B is correct.
Step-by-step explanation:
The requirement for at least 15 days' advance notice of an unfair trade practice hearing is crucial for ensuring procedural fairness and allowing the involved parties to adequately prepare their defense. This timeframe allows individuals or entities facing allegations of unfair trade practices to gather evidence, consult legal counsel, and formulate a comprehensive response to the charges.
Adequate notice is a fundamental aspect of due process, ensuring that parties have a reasonable opportunity to be heard and present their case before the regulatory body. This provision promotes transparency, fairness, and the overall integrity of the hearing process, aligning with principles of justice in administrative proceedings.
In summary, the correct answer is B) 15 days.
