Answer:
The lighthouse
Step-by-step explanation:
Personification is a common literary device in which an author gives human qualities to a thing, idea or animal. These attributes can take a variety of different forms, such as actions, feelings or thoughts of humans. In this case, the lighthouse is being personified because it is described as "winking." We know that winking is a quality that belongs to humans, and not to inanimate objects such as a lighthouse.
