C)elastically
D)shearingly

At higher temperatures, rocks are more likely to deform ductilely, meaning they can change shape without breaking. This is because high temperatures reduce a rock's resistance to deformation, allowing it to flow more easily. In contrast, brittle deformation (option B) occurs when rocks break under stress, which is less likely to happen at higher temperatures. Elastic deformation (option C) refers to the temporary distortion of a rock that returns to its original shape once the stress is removed, and shear deformation (option D) is a specific type of deformation where rocks slide past each other along a fault. While high temperatures can influence these types of deformation to some extent, neither is as directly related to temperature as ductile deformation.
