Which literary device involves non-humans acting like humans?

The correct answer is personification. This literary device gives human traits, emotions, or actions to non-human entities, allowing them to behave or be described in a way that makes them relatable or evokes empathy from the reader. For example, when a story describes the wind as "whispering" through the trees, it helps readers connect with the scene on a more personal level, as if the wind is engaging in a gentle conversation.

In contrast, while allegory tells a story with a deeper meaning, often using symbols, it does not specifically focus on human-like characteristics of non-humans. Metaphors compare two unlike things directly, while similes make a comparison using "like" or "as." Both metaphors and similes do not imply any human characteristics at all, making them different from personification.
