Which of the following does not represent an object?

A) URLs are objects on Diigo.
B) Dogs are objects on Dogster.
C) Secrets are objects on Whisper.
D) Places are objects on FourSquare.
E) Faces are objects on Facebook.

In the context of object-oriented programming or digital representation, an object typically refers to a data structure that represents a specific entity with attributes and behaviors. While URLs, dogs, secrets, and places can be represented as objects in their respective platforms (Diigo, Dogster, Whisper, FourSquare) because they have attributes and can have actions performed on them, faces on Facebook are not represented as standalone objects. Instead, faces might be part of a larger object, such as a photo or a user profile, but they are not independently treated as objects within the platform's data structure.
