What is a thesis statement?

• A. A broad overview of the topic.
• B. A concise claim expressing the main argument of an essay.
• C. A list of supporting examples.
• D. A conclusion summarizing the essay.

Answer: (B)

A thesis statement is a concise claim that expresses the main argument of an essay. It states your position on the topic and what you will argue or demonstrate in the paper, rather than just naming the topic. A strong thesis is specific and debatable, providing direction for the writing and guiding the evidence you’ll present. It helps keep the essay focused from the opening paragraph to the end.

Why this fits: it’s a single, defendable claim that you can support with reasoning and facts. The other ideas describe the topic in general, list supporting points, or summarize the essay—none of those are the central claim that the thesis provides.
