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

Richard wore a broad belt with shiny buckles.

A broad belt with shiny buckles was worn by Richard.

The correct passive form of the given sentence is A broad belt with shiny buckles was worn by Richard.

The active voice of the sentence is Richard wore a broad belt with shiny buckles. This sentence is in the simple past tense, which is used to describe an action that happened in the past. 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 "Richard" and the main verb is "wear." The past participle of "wear" is "worn." So, the passive form of the sentence is A broad belt with shiny buckles was worn by Richard.

The other options are incorrect because:

• A broad belt with shiny buckles had been worn by Richard. is in the past perfect tense, which is used to describe an action that happened in the past before another action happened. There is no other action mentioned in the sentence, so the past perfect tense is not appropriate.
• A broad belt with shiny buckles wore Richard. is grammatically incorrect. The subject of the sentence should be the object of the active sentence, which is "a broad belt with shiny buckles."
• A broad belt with shiny buckles was wear by Richard. is grammatically incorrect. The verb "to wear" is missing the past participle ending.
