If A,B,C are three integers and AB+C is even ; which of the following must be true? A)C is even B)B is even C)AB is Odd  Pick one
A) None of the above B) I only C) II only D) III only E) I,II only
If AB is Odd then C will not even. O+E = O   If B is even AB is even always. But If C is Odd E+O = O   None of the above are true.   None of the abovenswer : None of the above
