Which of the following is the best example of increasing an object's elastic potential energy?

Elastic energy is the potential mechanical energy stored in the configuration of a material or physical system as work is performed to distort its volume or shape. Elastic energy occurs when objects are compressed and stretched, or generally deformed in any manner. F or some solid objects applying forces such as, twisting, bending, and other distortions may generate thermal energy, causing the material's temperature to rise, increasing its elastic potential energy.
