How aboutnewid() = '00000000-0000-0000-0000-000000000000'
The question is not correct. Answer is 0 (zero).
The question asked which of the answers were possible outputs of the statement. It never stated that *all* of the possible outputs were listed as answers. Plus, is it even possible for NEWID() to return a value that's all zeroes?
