To answer this question, we need to understand the concept of verb tenses and the use of modal verbs.
Option A) "will be" - This option is incorrect because it uses the future tense, indicating that the outcome will be known in the future. However, the sentence states that the outcome will not be known until next week, suggesting that it is not known at the present moment.
Option B) "won't be" - This option is correct because it uses the negative form of the future tense to indicate that the outcome will not be known until next week. This aligns with the information given in the sentence.
Option C) "Option 1 or 3" - This option is incorrect because it is a combination of options A and D, which are both incorrect.
Option D) "have" - This option is incorrect because it uses the present perfect tense, suggesting that the outcome has already been known. However, the sentence clearly states that the outcome will not be known until next week.
Therefore, the correct answer is option B) "won't be." This option is correct because it accurately reflects the information given in the sentence that the outcome will not be known until next week.
