Answer:

The correct answer is Option C. Introduction - body - conclusion

A speech that will be coherent and captivating must have an introduction which suggests and lays the foundation for the subject or the title of the speech to be delivered.  

The introduction must seamlessly flow into the body of the speech where the facts, figures and details of the speech will be discussed. The body shows the detailed content.
