Select the correct passive form of the given sentence.

He has downloaded the movie on his phone.

The movie has been downloaded by him on his phone. 

The correct passive form of the given sentence "He has downloaded the movie on his phone" is The movie has been downloaded by him on his phone.

The active voice of the sentence is "He has downloaded the movie on his phone." This sentence is in the present perfect tense, which is used to describe an action that has happened in the past and is still relevant to the present. 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 "movie" and the main verb is "download." The past participle of "download" is "downloaded." So, the passive form of the sentence is "The movie has been downloaded by him on his phone."

The other options are incorrect because:

• The movie was downloaded by him on his phone." This sentence is in the past simple passive voice, which is used to describe an action that happened in the past. However, the action of downloading the movie is still relevant to the present.
• The movie is been downloaded by him on his phone." This sentence uses the present progressive passive voice, which is used to describe an action that is happening now but is not finished. However, the action of downloading the movie is not happening now.
• The movie are being downloaded by him on his phone." This sentence uses the plural form of the subject "movie." The subject of the sentence is singular, so the verb must also be singular.
