Final answer:
Option C "They sometimes make up customs and pretend they are real" best paraphrases the statement about inventing folklore. It reflects the intentional creation of narratives known as broken myths, which are shared for their underlying values.
Step-by-step explanation:
The paraphrased statement "...when they cannot discover folklore they enrich their beloved homes by inventing it." can be rephrased to option C: "They sometimes make up customs and pretend they are real." This reflects the creativity of individuals to conjure and perpetuate narratives or traditions that although fictitious, serve particular purposes or embody certain values, much like broken myths. Stories that are known to be untrue but are still shared due to the meaning they carry fall into this category, just as myths or literary fabrications can be both instructive and reflect societal norms, as noted in historical works by authors such as Columella or in philosophical discourses about the nature of truth in representation, as seen in the works of playwrights like Sophocles and Euripides.
