B) Isn’t
C) Hasn’t
D) haven’t

Answer 1

Hint: There are 3 main tenses in english Present, Past and Future and overall there are 12 tenses. Tenses primarily show the time of the action, its completion or its continuation. In the given sentence ‘it ‘ refers to some action. The first sentence shows that the action has taken place in the recent past. The second sentence has to be filled up in a way such that it will not happen again.

Complete answer:
Let us understand the related concepts-
Auxiliary verbs - These verbs are the helping verbs that are used along with the main verb. These words tell about the main verb’s attitude and tense. Modal verbs are also a form of auxiliary verbs.

The main forms of auxiliary verbs are:
- To Be which can take the form of am, is, are, was, were, being, been, will be
- To Have which can take the form of has, have, had, having, will have and
- To Do which can take the form of does, do, did, will do.
- Not is combined with auxiliary and modal verbs to show a denial of something. They combine in the form of at the end of auxiliary and modal verbs.

Let us analyze the given options:
A) Correct answer: Won’t is a combination of the auxiliary verb will +not. Since the word talks of negation of action in future, it gives grammatical sense to the sentence. Therefore this option is Correct.
B) Incorrect answer: Isn’t is a combination of the auxiliary verb is +not. Since it talks about present tense it is a grammatically incorrect option.
C) Incorrect answer: Hasn’t is a combination of the auxiliary verb has+not. Since it talks about present tense and it is a verb that shows possession it is a grammatically incorrect option.
D) Incorrect answer: Haven’t is a combination of the auxiliary verb have +not. Since it is a verb that shows possession, talks about present tense and uses plural form of the verb, it is a grammatically incorrect option.

Therefore the correct answer is option ‘A’.

Note: ‘Not’ in the above question is an adverb. It modifies the verb and shows negation. It is used with be, do, have, can, must to form negative verbs. It does not necessarily convey a negative meaning through this form.
