Potential energy is classified into which two energy?

Potential energy is the energy stored in an object due to its position or configuration. The two main types are gravitational potential energy (due to height in a gravitational field) and elastic potential energy (due to deformation of an elastic object, e.g., a spring). Option B incorrectly includes kinetic energy, which is a form of mechanical energy but not a type of potential energy. Option C uses 'mechanical' which is a category that includes both kinetic and potential energies. Option D is incorrect because option A is correct.
