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

The movie was being released on Friday.

They were releasing the movie on Friday.

The correct active voice of the sentence The movie was being released on Friday is They were releasing the movie on Friday.

The passive voice of the sentence is formed by putting the subject of the active sentence after the verb "to be" and the present participle of the main verb. In this case, the subject of the active sentence is "movie" and the main verb is "release." The past participle of "release" is "released." So, the passive form of the sentence is The movie was being released on Friday.

The active voice of the sentence is formed by reversing the order of the subject and verb, and removing the verb "to be" and the present participle. In this case, the active form of the sentence is They were releasing the movie on Friday.

The other options are incorrect because:

• The movie is being released on Friday. is in the present progressive tense, which is used to describe an action that is happening now but is not finished. The sentence is describing an action that happened in the past, so the present progressive tense is not appropriate.
• They are releasing the movie on Friday. is also in the present progressive tense.
• They have been releasing the movie on Friday. is in the present perfect tense, which is used to describe an action that has happened in the past but is still relevant to the present. The movie has already been released, so the present perfect tense is not appropriate.
