D Correct answer
Explanation

Speed = 250 m/min = 0.25 km/min. Distance = 96 km. For every 6 km: cycling time = 6/0.25 = 24 min, plus 6 min rest = 30 min per segment. Number of segments = 96/6 = 16. Total cycling time = 16 × 24 = 384 min. Rest periods = 15 intervals × 6 = 90 min. Total time = 384 + 90 = 474 min = 7 hours 54 minutes.
