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

The outcome of the interview will be published by next week.

The panel will publish the outcome of the interview by next week.

The correct active voice of the given sentence is The panel will publish the outcome of the interview by next week.

The passive voice of the sentence is The outcome of the interview will be published by next week. This sentence is in the simple future tense, which is used to describe an action that will happen in the future. The passive voice of the sentence is formed by putting the subject of the active sentence after the verb "to be" and the future participle of the main verb. In this case, the subject of the active sentence is "the outcome of the interview" and the main verb is "publish." The future participle of "publish" is "to be published." So, the passive form of the sentence is The outcome of the interview will be published by next week.

The active voice of the sentence is formed by putting the subject of the passive sentence before the verb and removing the verb "to be." In this case, the subject of the passive sentence is "the panel" and the main verb is "publish." So, the active form of the sentence is The panel will publish the outcome of the interview by next week.

The other options are incorrect because:

• The panel will have published the outcome of the interview by the week next. is grammatically incorrect. The preposition "by" should not be used with the phrase "the week next."
• The panel would have published the outcome of the interview by next week. is in the past perfect tense, while the original sentence is in the simple future tense.
• The panel was to publish the outcome of the interview by next week. is in the past infinitive, which is used to describe an action that was planned to happen but did not happen.
