訳 · Translation

I (unfortunately) left my important umbrella on the train.

正解 · Answer

わすれてしまった

解説 · Why

〜てしまう expresses completion often with regret. かさを電車にわすれてしまった = "I (unfortunately) left my umbrella on the train".

誤答 · Why the other options are wrong

わすれてある — 〜てある marks a deliberate resulting state, not an accident.

わすれておいた — 〜ておく means "do in advance on purpose" — wrong for an accident.

わすれてみた — 〜てみる means "try doing", which makes no sense here.
