Answer 2

Answer:

2) couldn't

He had such bad flu that he couldn't breathe through his nose.

Explanation:

• There exist specific words in English grammar that when added with main verbs, express the mood, mode, and attitude of the speaker, these are known as modal or modal auxiliaries/ modal auxiliary verbs.

• A modal verb expresses the mode of a verb that does not indicate any action and functions as a helping verb.

• Modals, modal verbs or auxiliary verbs are different from normal verbs.

• These verbs cannot work alone and principally function with the main verb.
• The so-called "semi-modals" work partially like modals and partially like main verbs.

• Modals don't use an 's' for the third person singular.

• They make questions by inversion ('You could do that.' becomes 'Could you please do that?').

• They are followed directly by the infinitive of another verb (without 'to')

• Examples include- can, could, will, would, shall, should, may, might, must, ought (to)

• "Can" and "Could" are the most commonly used modal auxiliary verbs.

• We use "Could" (past form of "can") to denote the ability to do something, Possibility, Request, Advice, and Condition.

• Here, in the given context, a condition where "He" failed to breathe through his nose is expressed as unable to breathe due to flu, the modal verb that will best explain this would be "Could not".

Therefore, option 2) couldn't is the most appropriate answer.
