C. -9
D. 1

1 answer

To determine which number has the greatest absolute value, we need to evaluate the absolute value of each option:

A. |5| = 5
B. |-3| = 3
C. |-9| = 9
D. |1| = 1

Now, comparing the absolute values:

  • For 5: absolute value is 5
  • For -3: absolute value is 3
  • For -9: absolute value is 9
  • For 1: absolute value is 1

The greatest absolute value is 9, which corresponds to option C, -9.

So, the answer is C. -9.
