A)-7

B)-3

C)3

D)7

To simplify the expression -|-5 + 2|, we need to follow the order of operations, which states that we should calculate the absolute value first, and then the negative sign.

The absolute value of a number is the distance of that number from zero on the number line. So, |-5 + 2| means we need to find the absolute value of -3.

The absolute value of -3 is always positive, so it is equal to 3.

Therefore, the simplified expression is -3.
