Which command in Karel's program allows him to turn to the right?

The command that allows Karel to turn to the right is the turnRight() function. In Karel's programming environment, movement commands are crucial for navigating the grid. Karel, by default, can only turn left using the turnLeft() command. To effectively manage turns, especially when needing to change direction to the right, the turnRight() command is specifically implemented for that purpose.

While turnLeft() allows Karel to pivot 90 degrees to the left, and turnAround() makes Karel turn 180 degrees by performing two left turns, these commands do not achieve a right turn directly. Additionally, the makeTower() command is unrelated to direction changes, as it concerns building structures rather than navigating Karel in any direction. Thus, the proper choice for making Karel turn right is indeed through the use of the turnRight() command.
