Compute the factorial function F(n)=! for an arbitrary nonnegative integer n. Since n!=1 by definition, from which of the following we can compute F(n) - F( n-1) n ?

A ) If n>1 return 0 else return F( n-1) * n

B ) If n> 1 return 1 else return F( n-1)*n

C ) If n= 0 return 1 else return F(n-1)*n ✅

D ) If n=1 return 1 else return F (n-2)*n
