Why does testing not prove a program is 100 percent correct (except for extremely simple programs)?

Because we can only test a finite number of cases, but the program may have an infinite number of possible combinations of inputs and outputs

Because the people who test the program are not the people who write the code

Because the program is too long

All of the above
