Choose the correct Indirect speech: The policeman said to the violent crowd, "Stop all this or you will be arrested"?

The policeman ordered the violent crowd to stop all that or they would be arrested

The policeman advised the violent crowd to stop or else be arrested

The policeman said to the violent crowd that they should stop or else be arrested

The policeman said to the violent crowd to stop all this or be arrested

The correct answer is: The policeman ordered the violent crowd to stop all that or they would be arrested.
This is the correct indirect speech equivalent of the original direct speech sentence. The verb "ordered" is used to report the command, and the wording "stop all that" and "they would be arrested" accurately convey the meaning of the original sentence.
