Let's analyze the code step by step, starting from Karel's initial position in the first row, third column, facing East.
1. **Initial Position**: Row 1, Column 3 (facing East)
2. **First Move**: Karel moves East to Row 1, Column 4.
3. **Second Move**: Karel moves East to Row 1, Column 5.
4. **Third Move**: Karel moves East to Row 1, Column 6.
5. **Turn Left**: Karel is now facing North.
6. **Final Move**: Karel moves North from Row 1, Column 6 to Row 2, Column 6.
So after executing the code, Karel ends up in **Row 2, Column 6**. Thus, the correct answer is:
**Row 2 and Column 6**
1. **Initial Position**: Row 1, Column 3 (facing East)
2. **First Move**: Karel moves East to Row 1, Column 4.
3. **Second Move**: Karel moves East to Row 1, Column 5.
4. **Third Move**: Karel moves East to Row 1, Column 6.
5. **Turn Left**: Karel is now facing North.
6. **Final Move**: Karel moves North from Row 1, Column 6 to Row 2, Column 6.
So after executing the code, Karel ends up in **Row 2, Column 6**. Thus, the correct answer is:
**Row 2 and Column 6**
