Given A={x,y}A = \{x, y\}A={x,y} and B={1,2}B = \{1, 2\}B={1,2}, which set represents the Cartesian product A×BA \times BA×B?
{(x,1),(x,2),(y,1),(y,2)}\{(x, 1), (x, 2), (y, 1), (y, 2)\}{(x,1),(x,2),(y,1),(y,2)}
{(x,y),(1,2)}\{(x, y), (1, 2)\}{(x,y),(1,2)}
{x,1,y,2}\{x, 1, y, 2\}{x,1,y,2}
{(1,x),(2,x),(1,y),(2,y)}\{(1, x), (2, x), (1, y), (2, y)\}{(1,x),(2,x),(1,y),(2,y)}
