I agree with A. On a number line, the negative numbers are listed backwards compared to the positive numbers. -3.25, even on a positive number line, is directly in between 3.2 and 3.3. One way you can visualize this is by adding a zero:
-3.30 -3.25 -3.20
_________________________ Since the negative numbers are reversed on a number line, you can easily see how the numbers go backwards, but are still in order.
