Final answer:
The absolute value of -68 is 68. Hence, A) is correct.
Step-by-step explanation:
The absolute value of a number is its distance from zero on a number line. For example, the absolute value of -3 is 3 because it is 3 units away from zero.
Similarly, the absolute value of -68 is 68 because it is 68 units away from zero. Therefore, the absolute value of -68 is 68, which corresponds to option A.
