Answer: will feel
Explanation: * The sentence expresses a hope for the future. 'Will' is used to express future actions or events. * 'feel' is incorrect because it implies a present or habitual action. * 'are going to be feel' is grammatically incorrect. The correct form would be 'are going to feel', but it doesn't fit the context as well as 'will feel'. * 'feels' is incorrect because the subject is 'you', which requires the base form of the verb. Therefore, 'will feel' is the most appropriate and grammatically correct option to complete the sentence. Full sentence: I hope you will feel better tomorrow.
