To determine whether Karel should put down the tennis ball if the world has dimensions of 1x1, you only need to check the condition once. In this scenario, the appropriate control structure to use would be an **If Statement**.
Here's why:
- **If** statement is used to execute a block of code based on a conditional check. Since you only need to check whether Karel is in a 1x1 world and then have Karel put down the ball, an If statement is sufficient.
- A **For Loop** is not necessary as you are not performing repetitive actions.
- A **While Loop** is also not appropriate since this situation does not involve repeated checks.
- An **If/Else statement** is excessive here, as there's no alternative action required if the condition is false.
- **None of these** would imply that none of the control structures would work, which is not true in this case.
Therefore, the correct answer is: **If Statement**.
