It looks like there might be a mistake in your question since you mentioned DJ has 16 movies and then stated "38 of them are comedies." This seems inconsistent because you cannot have 38 comedies within a total of 16 movies.
However, if we assume DJ has 16 movies and we need to determine how many are comedies, we would need more information to answer that question accurately, such as how many of those 16 movies are categorized as comedies.
In the context of the provided responses, if we take that DJ has 8 comedies within his collection of 16 movies, then the response would be:
8 movies
If that was not what you intended to ask, please clarify!
