Accepted Answer

Step 1: Write the word MOBILE with letter positions:
M(1), O(2), B(3), I(4), L(5), E(6)

Step 2: Arrange the letters in alphabetical order:
B, E, I, L, M, O

Step 3: Compare the original positions with the new positions:
- M was at position 1, now at 5
- O was at position 2, now at 6
- B was at position 3, now at 1
- I was at position 4, now at 3
- L was at position 5, now at 4
- E was at position 6, now at 2

None of the letters remain in their original position after arranging alphabetically.
