Which part of an informative essay introduces the main idea or topic?

A Body
B Conclusion
C Introduction
D Definition

C Introduction

The correct answer is C) Introduction.

To determine the correct answer, we need to understand the purpose of each part of an informative essay.

The introduction is the opening paragraph or section of an informative essay. Its main purpose is to introduce and grab the reader's attention. In this section, the writer provides background information and context about the topic, highlights the main idea or thesis statement, and outlines the structure of the essay. The introduction sets the tone for the essay and prepares the reader for what they will explore in the subsequent sections.

On the other hand, the body of the essay is where the writer presents detailed information, evidence, examples, and analysis to support the main idea or topic. The body usually consists of several paragraphs, each focusing on a specific aspect of the topic.

The conclusion, as the name suggests, is the final section of the essay. It summarizes the main points discussed in the body and restates the thesis statement in a way that leaves a lasting impression on the reader.

Lastly, the definition, though it can be included in the essay, is not a specific part of an informative essay. Definitions are often used to clarify key terms or concepts within the essay, but they do not introduce the main idea or topic.

In summary, the introduction is the part of an informative essay that introduces the main idea or topic.

C) Introduction
