What command would be used to debug Karel’s movements on the grid?

Using the command to print Karel's position is crucial for debugging the movements on the grid. The purpose of this command is to output Karel's current coordinates, allowing the programmer to verify that Karel is moving as intended. By having a visual representation of Karel's position, any discrepancies in movement can be easily identified and corrected.

This command enhances the debugging process by providing immediate feedback on Karel's location, which is essential for diagnosing issues related to Karel’s navigation. When checking for errors in simple moves or complex sequences, knowing where Karel is at each step helps ensure that the logic of the program is functioning correctly.

Other choices might suggest various forms of logging position or movements, but they do not directly indicate the specific action of printing the current coordinates, which is fundamental for effective debugging in this context.
