Correct Answer: Option E
Detailed Explanation:
The word 'DIARY' contains 5 distinct letters (D, I, A, R, Y).
The number of arrangements (permutations) of 5 distinct letters = 5! = 5 × 4 × 3 × 2 × 1 = 120.
Since 120 is not listed among options 1, 2, or 3, and option 4 states "More than one of the above" (which is also incorrect as none of the values 24, 5, or 10 equals 120), the correct answer is Option 5: "None of the above".
