Which of the following is an example of personification?

The correct answer is: The door protested as it opened slowly.

The correct answer is "The door protested as it opened slowly".
Among the two options given, only the first one shows the door - like an annoyed human being - protesting against its slow opening. Here, the door - a non-living thing - has been provided with personal attributes - complaining against something it dislikes - and thus, the sentence is expressing the simple meaning of the sound made by a door when it is opened slowly, but in a more ornamental and aesthetic manner. So, the correct answer is  "The door protested as it opened slowly".
