The correct answer is option A. "Short Story: A young hippo tells his story of growing so big that no home could hold him, so he sets out on his own to survive". Talking about pet overpopulation is not an easy task, because thousands of people love pets and the topic could be not well received for them. A short story that involves a hippo growing so big that no home could hold him is an effective disguise to talk about pet overpopulation, which is friendly, easy to understand and easy to relate with the topic.
