まどを __ __ ★ __ 。
🎉 Explanation

まどを あけ ない で ください。

English Explanation

The correct answer is `で` (de). This particle is used with the negative `ない` form of a verb (`あけない`) to create a polite negative request: `~ないでください` (Please don't ~). So, `あけないでください` means "Please don't open." `あけ` is the verb stem, which needs `ない` before `でください`. `ない` is already present before the star. `ください` is already present after the star. *Grammar Tip:* To politely ask someone not to do something, use a verb's `ない` form + `でください` (e.g., 食べないでください - Please don't eat).

日本語解説

正解は「で」。「~ないでください」で丁寧な禁止。「あけ」は動詞語幹。「ない」は既にあり。「ください」も文末。 文法:「ない形」+「でください」で「~しないでください」。
