Suppose $n$ and $p$ are unsigned int variables in a C program. We wish to set $p$ to $^nC_3$. If $n$ is large, which one of the following statements is most likely to set $p$ correctly? $p = n * (n-1) * (n-2) / 6;$ $p = n * (n-1) / 2 * (n-2) / 3;$ $p = n * (n-1) / 3 * (n-2) / 2;$ $p = n * (n-1) * (n-2) / 6.0;$
