A. 0
B. 1
C. 2
D. 5

When comparing two five digit whole numbers that are not equal, we start with the first digit, if these digits are the same, then we go to the second digit. When these digits are the same, then we go to the third digit. If the third digits are the same, we go to the fourth digit. If the fourth digits are the same, we go to the fifth digit. Since numbers are not equal, the last fifth digits must be different. Hence, the least number of place values is 1.

For example, comparing two numbers 12345 and 12346, we see that

1 = 1

2 = 2

3 = 3

4 = 4

and

5 < 6, then

12345 < 12346
