The squares marked A and B are exactly the same shade of gray. If you don't believe the answer, you can copy the image into a paint program and check the colors.

Or print the image out and cut out the squares and place them along side each other.  You will see they are identical in color.   Note that some printers have "enhancement" processing that increases the contrast of edges. This can cause the printed squares to have slightly different values of gray.
