Correct option is A
Step-by-step explanation:
A "current" medical exam report (DL-51) signifies that the medical examination was conducted within the last two years. Option A, or 2 years, is the correct time frame for the medical examination to be considered current. For individuals pursuing a commercial driver's license (CDL), keeping their medical examinations up to date is critical for maintaining the validity of their license and ensuring they meet the health requirements for safely operating commercial vehicles.
It's important for CDL holders to adhere to these medical examination requirements to ensure the safety and well-being of both the driver and others on the road.
