Explain how to find n!, where n is a positive integer. Choose the correct answer below. C O A. n! can be found by finding the product of all positive integers from n down through 1. O B. n! can be found by finding the product of all positive integers from n down through 1 and then subtracting n from that product. OC. n! can be found by finding the sum of all positive integers from n down through 1 and then dividing that sum by n. O D. n! can be found by finding the sum of all positive integers from n down through 1.
