Question

Which principal part is this verb form? (is) cutting A. past B. present participle C. past participle D. present

it wouldn't be a present particle because those often end with a (ing) and can't be past or past participle because that means its already been done so its present

Past often ends with -ed, or starts with had, or other words.
