Answer
A
n is less than negative 3 or n is greater than negative 2
B
negative 3 is greater than n comma n is greater than negative 2
C
2 is less than n comma n is less than 3
D
n is less than 2 or n is greater than 3

Explanation

For an absolute value to be greater than 1, its expression must be greater than 1 or less than −1. Solving 2n + 5 > 1 gives n > −2, and solving 2n + 5 < −1 gives n < −3. Therefore, the solution is n < −3 or n > −2, which is choice C.
