In option A the arrow is pointing in the correct direction. This is because the sentence is an active one that matches with the arrow pointing to the right. An active sentence is the one in which the voice is active, meaning that the verb written tell us that the subject is doing the action. In this case we can see that Tia (subject) shopped at the mall for a pair of shoes (action) and no the other way around. That is why the arrow should be in the right direction.
