Once you've taken it on, you should see it through to the end.

正解 · Answer

以上は

解説 · Why

〜以上（は） attaches to a completed commitment and introduces the speaker's judgment of duty: 引き受けた以上は、最後まで責任を持つべきだ ("now that you've accepted it, you must see it through"). The duty ending (べきだ) is the signature of this pattern.

誤答 · Why the other options are wrong

ばかりか — ばかりか means "not only… but also" and needs an additive second clause.

一方で — 一方で contrasts two coexisting aspects, not commitment and consequent duty.

上で — 上で means "after doing X (as a step)" — procedural, and does not pair with べきだ obligations this way.
