The correct answer is A. 40 minutes.

The target time for departing ART during day is 30 minutes. During night, the target time is increased to 40 minutes. This is because there is less traffic at night, so there is more time to depart. Additionally, the crew may need more time to prepare the aircraft for departure at night, as there is less daylight.

Option B is incorrect because the target time for departing ART during night is 40 minutes, not 50 minutes.

Option C is incorrect because the target time for departing ART during night is 40 minutes, not 60 minutes.

Option D is incorrect because the target time for departing ART during night is 40 minutes, not 45 minutes.
