If something is described as derivative, what does that imply?

Describing something as derivative implies that it is copied from another source or heavily influenced by existing works, rather than being original or unique. In literary or artistic contexts, a derivative work often borrows ideas, styles, or motifs from previous works, lacking the fresh and inventive qualities found in original creations. This term can carry a negative connotation, suggesting that the work does not contribute anything new or innovative to its field.

The other options do not align with the definition of derivative. For instance, indicating something is original or authentic contradicts the essence of what being derivative means, as those terms suggest a sense of novelty or genuineness that derivative works typically lack. Additionally, saying it is superior does not fit the connotation associated with derivative, as it typically does not imply a level of excellence but rather dependence on prior creations.
