Final answer:
The term is C) Fresco Restoration, which refers to the process of fixing and stabilizing original fresco artwork to bring it closer to its original state.
Step-by-step explanation:
The term for new paintings created based on the very dim surviving frescoes is C) Fresco Restoration. Unlike Fresco Duplication or Fresco Replication, which might imply creating a copy of the fresco on a new surface, restoration involves working on the original fresco itself. During restoration, conservators stabilize and fix the existing artwork, including returning the fresco closer to its original state. Particularly in reference to historical examples like buon fresco from the Renaissance, which involves applying pigment on wet plaster to chemically bond as it dries, the process may involve delicate procedures to reinforce and preserve the original artwork.
