A Correct answer
Explanation

Speed of boat in still water = 12 kmph. Rate of flowing water = 4 kmph. Upstream speed = boat speed - water speed = 12 - 4 = 8 kmph. Time given = 40 minutes = 40/60 hours = 2/3 hours. Distance = Speed × Time = 8 × (2/3) = 16/3 km = 5.33 km. This matches option A exactly.
