Explanation:

Number of ways of seating n people around a circular table is (n – 1)!.

Since initially all the chairs are similar, the first person can be seated in only 1 way. 

Once the first person is seated, all other 15 chairs are different, hence 15 people can be seated in 15! ways.

Hence the required answer = (16 – 1)! = 15!

Hence, option (b).
