a, then

No, the shadow makes the square marked B look lighter, because they're beside darker squares.

Get a bit of paper and cut a wee circle out, and hold it over the squares A then B. that lets your brain see them

without the comparison with any surrounding squares. . I think

How your brain can fool your eyes.

It is a good example of the brain doing what it does in making assumptions and generalisations to take shortcuts so you can act more quickly. If it didn't do this we would become paralysed through analysis and couldn't take action quick enough
