B Correct answer
Explanation

Statement I only gives the start time (2 pm) but no information about fill rate or initial state. Statement II tells us: 50% filled at 3 pm, 75% at 8 pm. The tank fills 25% in 5 hours, meaning it fills 50% in 10 hours. Since it was 50% full at 3 pm, it will be 100% full at 1 pm the next day. Statement II alone is sufficient.
