C. |–c| = 3 and –|d| = –4.
In mathematics, the absolute value or modulus of a real number is its numerical value without taking into account its sign, be it positive (+) or negative (-). Thus, for example, 3 is the absolute value of +3 and -3.
With c = -3 and d = 4
|–c| = |–(-3)| = |3| = 3
-|d| = -|4| = -4
