Arrange indices to spell a meaningful word Using the letters “G E D E M E N L C K N O W A T” at positions 1..15, choose the index order that forms a meaningful English word.

Introduction / Context:Index-ordering puzzles provide a fixed sequence of letters and ask you to pick an ordering of indices that concatenates into a meaningful word or phrase.

Given Data / Assumptions:

• Letters (1..15): 1=G, 2=E, 3=D, 4=E, 5=M, 6=E, 7=N, 8=L, 9=C, 10=K, 11=N, 12=O, 13=W, 14=A, 15=T.

Concept / Approach:Substitute each index sequence into the letters and read the result.

Step-by-Step Solution:Option (a): 14,9,10,11,12,13,8,4,3,1,2,5,6,7,15 ⇒ A C K N O W L E D G E M E N T ⇒ “ACKNOWLEDGEMENT”.Other options do not yield a common English word.

Verification / Alternative check:Spell out each option carefully; only (a) forms a standard, meaningful word.

Why Other Options Are Wrong:They produce non-words or scrambled fragments.

Common Pitfalls:Mis-mapping indices or missing repeated letters.

Final Answer:14, 9, 10, 11, 12, 13, 8, 4, 3, 1, 2, 5, 6, 7, 15
