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

The company sold the newly introduced car to the highest bidder.

The newly introduced car was sold to the highest bidder by the company.

The correct passive voice form of the given sentence "The company sold the newly introduced car to the highest bidder" is The newly introduced car was sold to the highest bidder by the company.

The active voice of the sentence is "The company sold the newly introduced car to the highest bidder." 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 "car" and the main verb is "sell." The past participle of "sell" is "sold." So, the passive form of the sentence is "The newly introduced car was sold to the highest bidder by the company."

The other options are incorrect because:

• The company sold the newly introduced car to the highest bidder." This sentence is in the active voice, but the passive voice is not required.
• The newly introduced car has sold to the highest bidder by the company." This sentence is in the present perfect passive voice, which is used to describe an action that has happened in the past and is still relevant to the present. However, the action of selling the car is not relevant to the present.
• The newly introduced car sold to the highest bidder by the company." This sentence is in the active voice, but the verb "sold" is in the wrong form. The correct form of the verb in the passive voice is "was sold."
