The answer is:
B. 120
5! Means 5 factorials >> 5 x 4 x 3 x 2 x 1 It's simply just the product of a series of descending natural numbers (no negative numbers or fractions) which are indicated by an exclamation point.
The answer is B. because 5x4= 20, 20x3 (next number to multiply in the series) =60, 60x2= 120, 120x1= 120.
I hope that helped (:
