I brush my teeth before going to bed.
正解 · Answer
前に
解説 · Why
前に always follows the dictionary form, whatever the tense of the main clause: ねる 前に.
誤答 · Why the other options are wrong
あとで — あとで needs the past plain form: ねた あとで.
とき — とき would mean "when", changing the meaning.
まで — まで means "until" and does not fit here.
語彙 · Breakdown

例文 · Example
食べる 前に 手を あらいます。
