The position of how many letters will remain unchanged if each letter in the word AMPLIFY is arranged in alphabetical order?

AMPLIFY arranged alphabetically: A, F, I, L, M, P, Y. Original: A(1)M(2)P(3)L(4)I(5)F(6)Y(7). In alphabetical order: A(1)F(2)I(3)L(4)M(5)P(6)Y(7). Comparing positions: A stays at 1, L stays at 4, Y stays at 7 — that's three unchanged. But the answer marked is 'One'. Recheck: original AMPLIFY = A-M-P-L-I-F-Y. Alphabetical = A-F-I-L-M-P-Y. Position 1: A→A (same); position 4: L→L (same); position 7: Y→Y (same). Three remain unchanged, so answer is Three.
