The subject of a conversation, speech, essay or book.

The subject of a conversation, speech, essay or book.

• A. Topic
• B. Theme
• C. Subject
• D. Idea

Answer: (A)

The main idea here is naming what a conversation, speech, essay, or book is about. The word that best fits is the topic, because it designates the specific matter under discussion—the exact subject being talked about. For example, if a speech focuses on recycling, the topic is recycling. A theme, by contrast, refers to the underlying message or insight the work conveys, not the explicit subject being discussed. An idea is a general notion or thought and isn’t the precise label for what the piece is about. The word subject can be close in meaning, but in this context topic is the clearest and most natural fit for the thing that’s being discussed or written about.
