Answer:
The correct choice is "Body - I. Geysers and Hot Springs of Yellowstone - A. Types of Geothermal Resources".
Step-by-step explanation:
The correct option which represents supporting detail is always in the body of the work/outline, where it is given more evidence and examples for the main idea presented before. In the "Body - I. Geysers and Hot Springs of Yellowstone - A. Types of Geothermal Resources" choice it is possible to notice this fact. This part provides examples for types of geothermal resources, such as "1. active geysers", "2. bubbling hot springs", and "3. volcanic holes". Letter B in this part is not the choice because it only provides examples of famous geysers around the world, which is not supporting detail about the main idea, although it is a real life evidence for the details given. Conclusion does not apply as a choice, too, because it is only the concluding points around the whole development made before.
