    Correct option is B

    Given:

    The word is POWERS , which consists of 6 letters: P, O, W, E, R, S , all distinct.

    Formula Used:

    The number of arrangements of n distinct letters is given by:

    n!=n×(n1)×(n2)××1n! = n \times (n - 1) \times (n - 2) \times \ldots \times 1

    Solution:

    6!=6×5×4×3×2×16! = 6 \times 5 \times 4 \times 3 \times 2 \times 1

    2. Calculate 6! :

    6! = 720
