Final answer:
The absolute value of -12 is greater than the absolute value of 8.
Step-by-step explanation:
When comparing absolute values, we are only interested in the magnitude or size of the numbers, regardless of their signs.
In this case, |-12| is equal to 12, and |8| is also equal to 8.
Since 12 is greater than 8, the correct statement is: a) |-12| is greater than |8|.
