Answer:
D
Step-by-step explanation:
To place into the category or to categorize something as a certain thing or as pertaining to a certain group is to consider. Saying that the literary work belongs to the select collection of works sufficiently well-known and appreciated to be classics is to state that the work is considered a classic.
The other options are not appropriate sin B says only some experts consider it to be a classic and C refers only to people who are aware of the work.
