The correct answer is: A. to working
The sentence “She is not used to work for so long” is grammatically incorrect. The verb “to work” should be in the infinitive form, which is “to work.” This is because the sentence is using the infinitive phrase “to work for so long” as a noun phrase. Noun phrases can be used as subjects, objects, or complements in a sentence. In this case, the noun phrase “to work for so long” is the subject of the sentence.
The other options are incorrect because they are not in the infinitive form. Option B, “to have worked,” is in the perfect infinitive form. The perfect infinitive form is used to express a past action that has a result in the present. In this case, the sentence is not expressing a past action that has a result in the present, so the perfect infinitive form is not correct. Option C, “to be working,” is in the present progressive infinitive form. The present progressive infinitive form is used to express an action that is happening at the moment. In this case, the sentence is not expressing an action that is happening at the moment, so the present progressive infinitive form is not correct. Option D, “No improvement,” is incorrect because the sentence is grammatically incorrect.
Here is a correct version of the sentence:
She is not used to working for so long.
