C Correct answer
Explanation

Virusoids are satellite nucleic acids that depend on helper viruses for replication. They are indeed non-coding molecules and some exhibit ribozyme activity (catalytic RNA). However, they do not have a capsid - that would distinguish them from viroids, which are also naked infectious RNA molecules.
