The correct option is "The language is inappropriate. "
In written language, the informative text is one in which the issuer (writer) briefly discloses facts, real circumstances or a particular issue to the receiver (reader). These texts are informative narratives of current events in an objective manner. In many cases, there is a difference with the expository text, since everyone pretends to present a specific topic, although the purpose of the informative is to explain or teach an event without using any resource.
