Answer: (C)

Alcohol impairs judgment, coordination, and reaction time, all of which are critical for safe drone operation. After heavy drinking, these effects can linger for many hours, so you must be free from the influence before flying. Nine hours is the minimum window suggested here; if you’ve had heavy drinking within nine hours of a flight, you may still be under its effects, making you unfit to operate. Shorter waits, like six hours, might not guarantee sobriety, while longer waits are more conservative. So, nine hours is the timeframe where you can reasonably expect residual impairment to still be possible if drinking was heavy.
