OA : B

Option A. 'Just because'? there are proper 'starters' than this. And it is not a proper idiom.This option is incorrect.

Option B. This option fully explains how 'King Alfred occupied and fortified London', in a simple and clear term. This makes the option perfect choice and thus it is the correct option.
