Solution:
The problem asks us to compare the position of the digits in the original number with their positions after the number is rearranged in ascending order.
1. Original Number: 6243514
2. Arranging in Ascending Order:
The digits in the number are 6, 2, 4, 3, 5, 1, 4. When arranged in ascending order, they become 1, 2, 3, 4, 4, 5, 6.
3. Comparison of Positions:
| Position | 1 | 2 | 3 | 4 | 5 | 6 | 7 |
|---|
| Original Number | 6 | 2 | 4 | 3 | 5 | 1 | 4 |
| Ascending Order | 1 | 2 | 3 | 4 | 4 | 5 | 6 |
| Unchanged? | No | Yes | No | No | No | No | No |
The position of the digit '2' at the second position remains unchanged.

| Original Position 1 | Original Position 2 | Original Position 3 | Original Position 4 | Original Position 5 | Original Position 6 | Original Position 7 |
|---|
| 6 | 2 | 4 | 3 | 5 | 1 | 4 |
| | | | | | |
| 1 | 2 | 3 | 4 | 4 | 5 | 6 |
| New Position 1 | New Position 2 | New Position 3 | New Position 4 | New Position 5 | New Position 6 | New Position 7 |
| Only the digit '2' at position 2 matches: 2 ↔ 2 | | | | | | |
The position of only one digit (2) remains the same.
Hence, the correct option is 3.
