The correct answer is D. The students viewed the movie before its regular showing.
Explanation:
In language, a prefix refers to an affix (letters, set of letters or a syllable) that is placed before a word and that add meaning to it. In the case of the prefix "pre-" this prefix mainly means before as in the word "prepublication" that means before the publication, "preadolescence" that means before the adolescence, among others. This means in the case of the word "preview" the prefix "pre-" means before and the word "view" means to see or observe and therefore "preview" in the sentence "The students were able to preview the movie" means that the students could see or view the movie before or in advance viewing and therefore this prefix indicates "The students viewed the movie before its regular showing".
