Answer 1

Hint: In this question you have to change the form of sentence from assertive to interrogative. Make sure that if the given sentence is in positive form then you have to change it in negative form. It must also have the same verb and tense as in the answer.

Complete answer:
A sentence whose grammatical form shows that it is a question is called an “interrogative sentence.”
A sentence that makes a statement is called an “assertive sentence.”
The given sentence is negative therefore, 'won't be' which is 'will not be' should be changed in positive form. Hence, the positive form of “will not be” is 'will be'.
The tense of the verb 'will be' has changed to present perfect 'Haven't you'. It's the negative form and this verb contradicts with the time when the action will take place: next week.
And also 'hadn't you' refers to the past perfect tense, whereas the given sentence is in the future tense.

Option A) This is not the correct option to be opted because this question is in negative form and as explained while changing the sentence from assertive into interrogative, we must change the negative form into positive form and vice - versa.
Option B) This is not the correct option to be opted because this question is in negative form and as explained while changing the sentence from assertive into interrogative, we must change the negative form into positive form and vice - versa.
Option C) This is not the correct option to be opted because this question is in negative form and as explained while changing the sentence from assertive into interrogative, we must change the negative form into positive form and vice - versa.
Option D) This is the correct option to be chosen because this interrogative is in the affirmative. And the interrogative sentence changes the negative form into positive form. Hence, the correct option to be opted.

Thus the correct answer is option ‘D’.

Note: When we change an assertive sentence to an interrogative, we change its form from a positive sentence to a negative sentence and a negative sentence into a positive sentence. An interrogative question always ends up with the question mark sign(?).
