A theme in literature is defined as the main idea, or main topic, proposed by a writer inside a text. It can be clearly mentioned, or it can be hidden within the use of words and meanings in a text and it can only be derived from analysis. There are two types of themes; the first one is the concept that readers derive from the work they are reading, in essence, what a readers thinks the writer is trying to put forth. Another, is the thematic statement, or literally, what the work really says about a subject. This is why the correct answer is B, A theme is the topic of the text.
