Answer:  D.  

720

Step-by-step explanation:

We know that the value of  n factorial or n! is given by :-

[tex]n!=n\times(n-1)\times(n-2)\times(n-3)\times...........................\times1[/tex]

We are given to find the value of 6! (or 6 factorial )

Using the above formula , the value of 6! is given by :-

[tex]6!=6\times(6-1)\times(6-2)\times(6-3)\times\times(6-4)\times(6-5)\\\\\Rightarrow\ 6!=6\times5\times4\times3\times2\times1\\\\\Rightarrow\ 6!=720[/tex]

Therefore , the value of 6! = 720
