41. Seven family members are seated around their circular dinner table. If only the only arrangements that are considered distinct are those where family members are seated in different locations relative to each other, then how many distinct arrangements around the table are possible?

(A) 7
(ÃŸ) 42
(C) 294
(D) 720
(E) 5040

Not sure if I understood the question but it seems like a circular permutation question.
Total arrangements =(n-1)! = (7-1)! = 720

Indeed this is a confusing question. does it ask to find arrangements in a circular arrangement or arrangement where the second arrangement wont have the same person seatign next to the same persons and on the same seat......

For circular arrangements no of ways = (n-1)! =6! = 720
