Solution

The correct option is B -4
$- 4 : - | - 13 - (- 17) | =$
$- | - 13 + 17 | =$
$- | 4 | = - 4$
Subtraction of negative $=$ addition
Note that the absolute value cannot be made into $13 + 17$ . you must perform the arithmetic inside grouping symbols first, whether inside parentheses or inside absolute value bars. Then you can remove the grouping symbols.
