“Expectant” is an adjective describing a person who expects something. (For example, “The expectant crowd watched the basketball hover on the rim of the hoop.”) Here we need the plural noun form, “expectations”. We are satisfied when something meets our expectations and disappointed when it does not.
彼らの仕事が私たちの期待に応えられなかったので、契約を破棄しなければならなかった。
「Expectant」は何かを期待する人を表す形容詞です。(例えば、期待に満ちた観客がバスケットリングの縁に浮いたボールを見ていた。)問いでは、複数形の名詞「expectations」が当てはまります。期待に応えたら満足しますし、応えられなかったら失望するものです。
