The factorial of an integer is the product of that integer multiplied by all the positive non-zero integers less than that integer. So, 5! ! is the mathematical symbol for factorial) is 5 * 4 * 3*2*1. 4! is 4*3*2*1, so 5! could be written as 5*4!. So a recursive definition of factorial is n! is n*n-1) !, as long as n >1. 1! is 1. What is the recursive call for this function fact) ?

• A) factn)*n;
• B) factn-1)*n;
• C) n-1)*factn)
• D) factn-2)*n-1)
