Answer:
The correct answer is D. It is false that information found in editorials is usually extremelly detailed and lengthy.
Explanation:
Editorials belong to the narrative genre, and consist of expository-argumentative texts, usually not signed, that explain, evaluate and judge a news event of special importance.
An editorial is a collective opinion, an institutional judgment formulated in accordance with the ideological line of the media. In other words, it is an opinion or comment made by the editor about the news, and written according to the experiences of the editor or the editors.
Due to this characteristics, editorials are not made for informative purposes, so information found in them is not extremely detailed but largely influenced by the opinion of who writes the article.
