Answer
Correct choice: (C)
正确答案：（C）
Solution
The digit 9 is in the hundreds place (value 100), the digit 3 is in the thousandths place (value 0.001). \(100 / 0.001 = 100{,}000\). Each place shift is a factor of 10, and there are 5 shifts.
数字 9 在百位（值 100），数字 3 在千分位（值 0.001）。\(100 / 0.001 = 100{,}000\)。每位移动一次是 10 的倍数，总共 5 次移动。
