The correct answer is: Jeremiah buried a linen belt and dug it up after it had begun to rot to demonstrate Judah’s spiritual rottenness.
This specific act is described in Jeremiah 13:1-11, where God instructs Jeremiah to buy a linen belt, wear it, and then bury it. When he retrieves it later, it is ruined, symbolizing how Judah has become worthless due to their disobedience and wickedness. The other options do not accurately reflect the actions taken by Jeremiah as recorded in the Book of Jeremiah.
