Letter-ordering (forms a meaningful English word): Given letters with fixed positions — E(1) C(2) O(3) T(4) I(5) H(6) T(7) Y(8) H(9) O(10) N(11) P(12) A(13) — which index sequence produces a valid word?

Introduction / Context:
We again select the index order producing a real English word from a longer letter sequence.

Given Data / Assumptions:

• Map: 1→E, 2→C, 3→O, 4→T, 5→I, 6→H, 7→T, 8→Y, 9→H, 10→O, 11→N, 12→P, 13→A.

Concept / Approach:
These letters can spell “HYPOTHECATION,” a finance/legal term meaning pledge of property as security.

Step-by-Step Solution:
Option D yields indices 9,8,12,3,7,6,1,2,13,4,5,10,11 → H, Y, P, O, T, H, E, C, A, T, I, O, N = “HYPOTHECATION”.

Verification / Alternative check:
Spelling matches the standard word exactly; every letter is drawn from the provided positions in correct frequency.

Why Other Options Are Wrong:
They do not spell a standard dictionary word.

Common Pitfalls:
Misplacing the two H’s or the sequence “…THECATION”.

Final Answer:
9, 8, 12, 3, 7, 6, 1, 2, 13, 4, 5, 10, 11
