This machine has good efficiency.
正解 · Answer
効率
解説 · Why
こうりつ (efficiency) is 効率 — 効 (effect) + 率 (rate). Common traps swap in 交/功 or 律.
誤答 · Why the other options are wrong
交率 — 交 (こう, to cross) is the wrong first kanji.
功率 — 功 (こう, merit) is a homophone trap; the word uses 効.
効律 — 律 (りつ, law/rhythm) is the wrong second kanji.
