In this question we have a pool starting at 1.1.128.1 ending 1.1.135.254.

Book offers B as the correct as the correct answer claiming our block size is 64.
How do we get that result?

I would say it could be a block of 128 if we get use question C which also seems correct.
Also it could be a block of 8 but there is no prefix-length 21 answer.

Can you please explain in detail the books answer ?
