After running a specific code, how many tennis balls will there be at a location if Karel is initially there with one ball?

In Karel programming, when Karel starts with one tennis ball, the total number of balls at that location depends on the actions performed in the code executed. If no commands were issued to drop or remove the ball, Karel will still have that one ball at the location after running the code.

For option B to be the correct answer, it implies that Karel has not executed any commands that would modify the number of tennis balls present at that location, such as dropping a ball or picking one up. Since Karel began with one ball and there were no additional actions affecting the ball count, the outcome remains the same: there is still one tennis ball at Karel's location.

Thus, the total number of tennis balls at that spot is indeed one, confirming option B as the correct answer.
