which control structure do you need to use?
for loop
while loop
if statement

none of these

Explanation:

An If Statement is used to execute code when a certain condition is met. Here, the condition is "Karel is not able to move forward in the direction they are currently facing", and when this condition is true, Karel should put down a tennis ball. Loops (For and While) are used for repetitive tasks, and an If/Else statement is used when there are two - alternative actions based on a condition. Since only one action (putting down a ball) is needed when the condition is true, an If Statement suffices.

Answer:

C. If Statement
