What is the difference between gravitational and elastic potential energy?

• Gravitational potential energy is due to motion, while elastic potential energy is due to stretching or compression
• Gravitational potential energy is due to stretching or compression, while elastic potential energy is due to position in a gravitational field
• Gravitational potential energy is due to position in a gravitational field, while elastic potential energy is due to stretching or compression.
• Gravitational potential energy is due to temperature, while elastic potential energy is due to position
