B Correct answer
Explanation

The word WEDDING has 7 letters with D repeated twice. Number of arrangements = 7!/2! = 5040/2 = 2520. We divide by 2! because the two D's are identical and swapping them doesn't create a new arrangement. This is the standard formula for permutations with repeated elements.
