Select the option that expresses the given sentence in passive voice.

Where can I find the way to the library?

Where can the way to the library be found?

The correct option that expresses the given sentence in passive voice is: Where can the way to the library be found?

The active voice of the sentence is Where can I find the way to the library? This sentence is in the interrogative mood, which is used to ask a question. 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 "I" and the main verb is "find." The past participle of "find" is "found." So, the passive form of the sentence is Where can the way to the library be found?

The other options are incorrect because:

• Where can they be found in the library? is in the active voice, but the subject of the sentence is "they." This is not correct because the way to the library is not a person.
• They cannot be found in the way to library? is grammatically incorrect. The verb "cannot" should not be used with the past participle of the verb "find."
• Who can found with the way to library? is grammatically incorrect. The verb "found" should not be used with the preposition "with."
