In which set are the numbers arranged in ascending order? (1 point)

To determine which set of numbers is arranged in ascending order, we need to convert all numbers into the same form for easier comparison.

### Set A:
- 0.00125
- 0.00225
- 0.000325
- 0.00325

Ordering: 0.000325, 0.00125, 0.00225, 0.00325 (not in ascending order).

### Set B:
- 3.25 × 10^-3 = 0.00325
- 2.25 × 10^-3 = 0.00225
- 3.25 × 10^-4 = 0.000325
- 1.25 × 10^-3 = 0.00125

Ordering: 0.000325, 0.00125, 0.00225, 0.00325 (not in ascending order).

### Set C:
- 0.000325
- 0.00225
- 0.00125
- 0.00325

Ordering: 0.000325, 0.00125, 0.00225, 0.00325 (not in ascending order).

### Set D:
- 3.25 × 10^-4 = 0.000325
- 1.25 × 10^-3 = 0.00125
- 2.25 × 10^-3 = 0.00225
- 3.25 × 10^-3 = 0.00325

Ordering: 0.000325, 0.00125, 0.00225, 0.00325 (in ascending order).

Thus, **Set D** is arranged in ascending order.
