The inner-most layer of the Earth is known as the Asthenosphere. Although all four options relate to different layers of the Earth, only the Asthenosphere is located at the inner-most part.

1. Lithosphere refers to the rigid outermost layer of the Earth, which consists of the crust and a part of the upper mantle.

2. Mesosphere is a region found in the Earth`s atmosphere, not the inner layers of the Earth.

3. The Asthenosphere is a layer located below the lithosphere and is characterized by partially molten rock that is able to flow slowly over time.

4. Barysphere is not a term commonly used in Earth science. It may be a typo or a term used in a different context.

Therefore, the correct answer is option 3, Asthenosphere.
