The following code examine three variables -- x and y -- and prints the largest multiple of 15 among them. If none of them is a multiple of 15, it prints a message to that effect. def largestMultiple(x,y): """ x and y are numbers Returns the maximum number of x and y that is a multiple of 15. If none of them is a multiple of 15, return None """ found15 = False largest = 0 if x % 15 == 0 : largest = x found15 = True if y % 15 == 0 : if not found15 : largest = y found15 = True elif y > largest : largest = y if found15 : return largest else : return None Assume that largestMultiple is called with numbers as arguments. Which of the following test suites would make a path-complete glass box test suite for largestMultiple? (1 correct answer only) Question 4 options: Test Suite A: largestMultiple(20,10), largestMultiple(20,15), largestMultiple(30,60), largestMultiple(30,15), largestMultiple(30,45) Test Suite B: largestMultiple(40,10), largestMultiple(40,30), largestMultiple(45,50), largestMultiple(45,15), largestMultiple(45,30) Test Suite C: largestMultiple(40,10), largestMultiple(40,30), largestMultiple(45,10), largestMultiple(45,15), largestMultiple(45,40) Test Suite D: largestMultiple(20,10), largestMultiple(20,15), largestMultiple(30,10), largestMultiple(30,15), largestMultiple(30,45)
