B Correct answer
Explanation

Ballu traveled 48 km 2 hours faster than planned. His actual speed was 1 km/hr more than intended for every 1 hr 15 min. Intended speed per 1.25 hrs = 10 km, so intended speed = 8 km/hr. Planned time = 48/8 = 6 hours. Actual time = 6 - 2 = 4 hours. Actual speed = 48/4 = 12 km/hr.
