A sled slides across a patch of rough grass and comes to a stop.
Which row in the table correctly describes the changes in the energy stores?
| Decreases | Increases | |
|---|---|---|
| A | kinetic energy store of the sled | chemical energy store of the sled |
| B | kinetic energy store of the sled | thermal energy store of the sled and grass |
| C | thermal energy store of the sled and grass | kinetic energy store of the sled |
| D | thermal energy store of the sled and grass | chemical energy store of the sled |
