Select the correct passive form of the given sentence.

The maid washes the windows eve

The windows are washed every week by the maid.

The correct passive form of the given sentence The maid washes the windows every week is The windows are washed every week by the maid.

The active voice of the sentence is The maid washes the windows every week. This sentence is in the simple present tense, which is used to describe an action that happens regularly or habitually. The passive voice of the sentence is formed by putting the subject of the active sentence after the verb "to be" and the past participle of the main verb. In this case, the subject of the active sentence is "windows" and the main verb is "wash." The past participle of "wash" is "washed." So, the passive form of the sentence is The windows are washed every week by the maid.

The other options are incorrect because:

• The windows are wash every week by the maid. has a typo. The past participle of "wash" is "washed," not "wash."
• The windows were washed every week by the maid. is in the past tense, but the action of the windows being washed happens regularly or habitually. The simple present tense is more appropriate in this case.
• The windows was washed every week by the maid. is in the singular form, but the subject of the sentence is plural.
• The windows washed every week by the maid. is missing the verb "to be." The passive voice of the sentence must include the verb "to be."
