Which command would you use to safely navigate around a blocked path?

The command to safely navigate around a blocked path is to turn around. Using turnAround() allows Karel to reverse direction completely, thereby avoiding any obstacles that may be blocking the current path.

This command effectively reorients Karel so that it is facing the opposite direction, which can be essential for finding an alternate route or maneuvering back to a previous position to explore other possibilities.

In contrast, moving forward might lead Karel directly into the obstruction, and turning left or right may not provide the required clearance if the path is blocked ahead. Thus, turnAround() is the most logical and safe choice for navigating around a blockage.
