A hapten is a small molecule that can elicit an immune response only when attached to a large carrier such as a protein. The carrier can also be one that does not elicit an immune response by itself. Things such as infectious agents, or insoluble foreign matter can elicit an immune response in the body as well as large lolecules.
The term "hapten" does not belong in the list because it is not a complete antigen. Haptens are small molecules that can bind to antibodies, but they are unable to induce an immune response on their own.
A hapten is a small molecule that can elicit an immune response only when conjugated with a large carrier such as a protein. Typical haptens include drugs, urushiol, quinone, steroids, etc. This is what I read on Creative Biolabs.
Penicillin is considered a hapten because it is a small molecule that, on its own, does not elicit an immune response. However, when it binds to larger proteins in the body, it can form a complex that the immune system recognizes as foreign, triggering an allergic reaction. This ability to bind to proteins and modify them enables penicillin to act as a hapten, leading to sensitization and potential allergic responses in susceptible individuals.

Because the molecule is too small to cross-link with immune-cells
