In Karel programming, which command is used to stop Karel from executing?

In Karel programming, the command that correctly stops Karel from executing further instructions is "halt()". This command is designed to immediately terminate the execution of Karel’s program. When Karel encounters "halt()", it will cease its operations entirely and will not continue with any subsequent commands.

The other options, while they might seem plausible, do not represent valid commands to stop Karel's execution in this programming context. Understanding the termination command is crucial for controlling the flow of Karel’s actions effectively, especially when you need to ensure that the program does not proceed under certain conditions.
