Physics

When you stretch a spring, you are increasing the elastic potential energy.

Elastic potential energy is stored as a result of the deformation of the spring (whether it's stretched or compressed) and is recoverable when the spring returns to its original shape.

Option A, Gravitational potential energy

Stretching a spring does not change the height of the spring (assuming it is not lifted vertically during the stretching process), so the gravitational potential energy does not change due to the stretching of the spring.
