💡 Detailed Explanation
The verb '余る' (amaru) means 'to remain', 'to be left over', or 'to be in excess' after using what is necessary. The correct usage is '料理を作りすぎて、たくさん余ってしまった' (I made too much food, and a lot of it was left over). The other contexts do not match the definition or grammar of '余る'.
