The answer is D. A verb that starts with "to" is in an infinitive verb form. It should be noted that a verb in this form does not function as a verb instead it functions as another part of speech. Infinitives can function as adverbs, adjectives or as nouns.
<span>B maybe the correct answer, only because the last choice has a comma at the end and not a period. (but if you just made a typo while copying and its supposed to be a period, then that's the answer.)</span>
In subjunctive mood, a verb would be doubtful or un-factual.
