The answer is A. The lithosphere is rigid and immovable, and the asthenosphere is hot and flowing. The lithosphere rides on the asthenosphere. The asthenosphere is solid upper mantle material that is so hot that it behaves plastically and can flow. Lithosphere is both crust and a portion of the upper mantle, this behaves as a brittle, rigid solid also this is act as a mechanical layer in the outermost.
