Emergency lights will be powered for approximately ___ during an emergency.

• A. 10 minutes
• B. 5 minutes
• C. 15 minutes
• D. 30 minutes

Answer: (A)

Emergency lights provide a reliable light path to exits after a power loss, so people can see and move to safety during an evacuation. The duration reflected in the scenario is the amount of time the lighting is expected to stay powered to support that immediate evacuation. In this question, the assumed window is about ten minutes, making ten minutes the best match among the options. A shorter period could leave the path less well-lit for the full evacuation, while longer periods imply more extensive backing than the scenario requires.
