The right answer to the quiz is A.
Translation:
Mén kāi zhe, jìnlai ba.
Boss: 门 开 着，进来 吧。
The door is open, please come in.
Lǎobǎn, zhè shì nín yào de wénjiàn.
Mike: 老板， 这 是 您 要 的 文件。
Sir, here are the documents you wanted.
Analysis:
The word “着 (zhe)” here is a dynamic auxiliary word. When used after a verb, the auxiliary “着 (zhe)” acts like the -ing ending in English; it creates the present participle. The expression “开着” in the conversation shows that the door is open.
Examples:
Mèimei zài chuángshang tǎngzhe.
妹妹 在 床上 躺着。
The little sister is lying on the bed.
Xiǎomāo zài chuāngtáishang pāzhe shuìjiào ne.
小猫 在 窗台上 趴着 睡觉 呢。
The kitten is lying on the sill asleep.
