Katie's flawed reasoning is most similar to that in answer C. In the original passage, Katie thought she knew that Joel had gone shopping because she saw bananas, apples, and bread, since Joel always buys those items when he goes shopping. However, she did not know that Joel had gone shopping; she only knew that the food had arrived. This is most similar to C, in which Elena knows that Emily always brings a pie, and assumes Emily is there when she sees a pie, even though the pie could have been brought by someone else.
