Knocking a nail into a wooden block with a hammer involves conversion between different forms of energy, which of following choices present this conversion in correct order.

• A. chemical energy → gravitational potential energy → kinetic energy → (sound energy + heat energy)
• B. chemical energy → kinetic energy → gravitational potential energy → (sound energy + heat energy)
• C. chemical energy → (sound energy + heat energy) → kinetic energy → gravitational potential energy
• D. (sound energy + heat energy) → chemical energy → kinetic energy → gravitational potential energy
