Reveal answer Fill a bubble to check yourself
C Correct answer
Explanation

The minimum possible values for x1 through x10 are 1, 2, 3, ..., 10 (since they must be distinct positive integers in increasing order). The sum of 1+2+...+10 = 55. Since the integers could be arbitrarily large, there's no upper bound. Therefore S >= 55.
