• A. Replacing the entire smoke alarm.
• B. Inspecting the system, cleaning and testing the alarm, and replacing batteries according to the manufacturer's instructions.
• C. Only testing the alarm.
• D. Only cleaning the alarm.

Answer: (B)

Regular maintenance of smoke alarms means doing all the standard upkeep tasks that keep the unit reliable: inspect the system, clean and test the alarm, and replace batteries according to the manufacturer's instructions. This full set ensures the alarm is physically present, free of dust or debris that could prevent it from sounding, functioning properly when tested, and powered correctly.

The best choice includes all these elements, which is why it’s correct. Replacing the entire smoke alarm is not routine maintenance unless the unit is faulty or past its expected life. Only testing or only cleaning the alarm misses essential steps that affect safety and reliability.
