Number of circular permutations of different things taken all at a time is n!.
Answer: B
The claim is false. Circular permutations of \( n \) distinct objects number
\[ (n-1)! \]
not \( n! \). In a circle there is no fixed starting point, so the \( n \) rotations of any arrangement all look the same - fixing one object's position removes that redundancy and leaves \( (n-1)! \).
