help me which one is the right on is a or b or c or d

Answer:
The correct answer is 10 blocks east
Suggestion:
I suggest using a graph. It is much easier. just start at the center (0,0) and move 10 left, 10 down, 10 up, and then you can see you just need to go 10 right to get back to the center, or in this situation The Pizza Parlor.
