Which of the following statements must be true whenever n, a, b, and c are positive integers such that n < a, c > a, and b > c ?
A. a < n
B. b – n > a – n
C. b < n
D. n + b = a + c
E. 2n > a + b
b is true, since b is larger than a. we see this from the 2 last statements. n is subtracted form both of them, so b is still larger, and b-n is larger than a-n
