What would happen if you omitted the if statement that checks for balls in the Cleanup Karel example?

• A. Karel would still attempt to take balls, if present
• B. Karel would leave remaining balls on the ground
• C. Karel would stop executing the program
• D. Karel would automatically pick all balls

Answer: (B)

Omitting the if statement that checks for balls in the Cleanup Karel example would lead to Karel leaving remaining balls on the ground. The purpose of the if statement is to determine whether or not Karel should attempt to pick up a ball. Without this check, Karel would not be able to verify if a ball is present before trying to pick it up. As a result, Karel might simply move around without having any logic to address the actual presence of balls, which means that any balls left on the ground would remain uncollected. This scenario emphasizes the importance of conditional statements in programming, particularly when specific actions depend on certain conditions being met.
