Answer:
body

The body gives reasons because it is where you give evidence and reasoning. The introduction just introduces a topic while a the thesis does the same. The conclusion ends the writing so the only logical answer is the body.
After reading the excerpt represented above, I would say that the most appropriate word that coincides with tone of the text is <span>Demands. At first : there is a business term called false demands, which is commonly used in economics/international relationships.
