The correct option is A before

A conjunction is a word used to connect words, clauses or phrases.

'Before' is used to state 'previously to the time when. The given sentence talks about the activity done before going to bed.

'As soon as' is used to show that something happens immediately, i.e. ‘at the very moment another action is completed’, or ‘shortly after another action is completed'.
