Correct answer: D
CONCEPT
When the letters of a word are rearranged alphabetically, a position remains unchanged only if the letter at that position before sorting is the same as the letter at that position after sorting.
Compare the original and sorted sequences position by position, and count the exact matches.
APPLICATION
Write the original sequence: F, R, I, E, N, D.
Arrange the letters in ascending alphabetical order: D, E, F, I, N, R.
Compare the letters at each of the six positions.
Position | Original | Sorted | Comparison |
|---|---|---|---|
1 | F | D | Different |
2 | R | E | Different |
3 | I | F | Different |
4 | E | I | Different |
5 | N | N | Same |
6 | D | R | Different |
CROSS-CHECK
The sorted sequence is in ascending order D < E < F < I < N < R. Only the fifth position contains N in both sequences, so the count of unchanged positions is one.
Result: One letter position remains unchanged.
