Let's break down what Karel's movements look like based on the code provided:

  1. Starting Position: Row 1, Column 1, facing East.
  2. First Command (move();): Karel moves East to Row 1, Column 2.
  3. Second Command (move();): Karel moves East again to Row 1, Column 3.
  4. Third Command (turnRight();): Karel turns to face South.
  5. Fourth Command (move();): Karel is now facing South and moves to Row 2, Column 3.

After executing all these commands, Karel will end up at Row 2, Column 3.

Thus, the correct answer is:

Karel ends on Row 2, Column 3.
