The zero product property says that if a product of two real numbers is 0, then one of the numbers must be 0. (a) Which of the following expresses the zero product property formally using quantifiers and variables? O v real numbers x and y, if x = 0 and y = 0 then xy = 0. O v real numbers x and y, if xy = 0 then x = 0 and y = 0. O v real numbers x and y, if xy = 0 then x = 0 or y = 0. O v real numbers x and y, if x = 0 or y = 0 then xy = 0.
