Write the original word and alphabetized word one above the other, then count characters that occupy the same position in both sequences.
List the original word
Original positions: 1:D, 2:I, 3:S, 4:P, 5:L, 6:A, 7:Y
Sort the letters alphabetically
Arranging D, I, S, P, L, A, Y in English alphabetical order gives: 1:A, 2:D, 3:I, 4:L, 5:P, 6:S, 7:Y
Compare positions
1(D vs A), 2(I vs D), 3(S vs I), 4(P vs L), 5(L vs P), 6(A vs S), 7(Y vs Y). Only the 7th letter (Y) remains in the same position.
A: 2 is incorrect because only 1 letter remains unchanged. B: 0 is incorrect because there is 1 match. D: 3 is incorrect as only Y matches the original index.
C is correct because only the letter Y remains in its original 7th position when the word DISPLAY is rearranged alphabetically as ADILPSY.
When checking for 'unchanged positions', always write the original word and the target arrangement vertically or aligned in columns to avoid manual tracking errors.
