It goes 3 blocks west then 8 blocks east, so it goes 5 blocks east in total.
It goes 4 blocks north and 1 block south, so it goes 3 block north in total.
So to return to its original position, it must go 5 blocks west and 3 blocks south. Therefore, your answer is the fourth choice, (x,y) ----> (x-5,y-3)
