192.168.64.0/20, and 192.168.96.0/20.Which subnet ID can you use if you need to sup-port another subnet with this RRAS server?A. 192.168.20.0/20B. 192.168.40.0/20C. 192.168.48.0/20D. 192.168.60.0/20C.The subnet mask of 20 bits means that the first two octets and the first four bits ofthe third octet are used to define the subnet ID.The rightmost bit of the four bits usedin the third octet represents a value of 16. Each subnet ID must therefore have a valuein the third octet that is divisible by 16.The only one in the list that meets this crite-rion is Answer A.A, B, DThese answers are incorrect because none of them meets the criterion. InAnswer A, 192.168.20.0/20, the 20 in the third octet is not divisible by 16.The samesituation exists for Answer B, 192.168.40.0/20.The 40 in the third octet is not divisibleby 16. Finally, in Answer D, 192.168.60.0/20, the 60 in the third octet is not divisible by
