B Correct answer
Explanation

The sequence follows a pattern where the difference between consecutive terms increases by 1: 0 to 1 (+1), 1 to 3 (+2), 3 to 6 (+3), 6 to 10 (+4), 10 to 15 (+5). The next difference should be 6, so 15 + 6 = 21. Option A (19) would require a difference of only 4, breaking the pattern.
