Answer:
a-) no longer is
Step-by-step explanation:
- Choice a-) is the best answer. The statement states that "He was used to smoking". This lets us know that in the past he was used to smoking. In the present, or now as the statement puts it, he no longer is. It makes more sense to use the present tense.
- Choice b-)is not the best answer. The statement states that "He was used to smoking". This lets us know that in the past he was used to smoking. However, placing "is" before no longer would only be appropriate if the subject was actually doing something. The sentence is simply describing how his perspective has changed.
- Choice c-) is incorrect. The statement states that "He was used to smoking" which is in the past tense. In the present, or now as the statement puts it, he no longer is. "He no longer was" is the past tense which wouldn't make sense in this context.
- Choice d-) is incorrect. The statement states that "He was used to smoking" not "He used to smoke." Therefore, there is not enough context to state that the narrator no longer smokes.
