When we test this function, which tests will fail? def sum_abc (a: int, b: int, c: int) -> int: "Return the sum of a, b and c if the three values are different. If exactly two of the values are the same, that value isn't used when the sum is calculated. If all three values are the same, return 0. TFT result = a + b + c if a == c or a == b: return result 2 * a if b == return result 2 * b if a == b and b return 0 return result Select one: O The tests in which all three arguments are the same. The tests in which all three arguments are different or two of the three arguments are the same. The tests in which all three arguments are different. The tests in which two of the three arguments are the same or all three arguments are the same. The tests in which exactly two of the three arguments are the same. The tests in which all three arguments are the same or all three arguments are different
