According to the leadership handbook, a public speech should have three basic parts:

The correct answer emphasizes the essential structure of a public speech, which consists of three fundamental components: the introduction, body, and closing.

The introduction is crucial as it sets the stage for the audience, establishes the speaker's credibility, and provides a preview of the main points that will be discussed. This part captures the audience's attention and helps them understand the purpose of the speech.

The body is where the main content lies. It contains the key messages the speaker wants to convey, supported by evidence, examples, and elaboration. This section is vital for building the argument or narrative and ensures that the audience is engaged and informed.

The closing wraps up the speech, reinforcing the main points made in the body and providing a final takeaway for the audience. It is an opportunity to emphasize the significance of the message and leave a lasting impression.

Together, these three parts form a coherent and impactful speech structure that helps communicate ideas effectively to the audience. Other options either miss key components or present elements that are not typically part of the conventional public speaking framework.
