The particles that don't have nucleic acid as their hereditary material:

Explanation

Prions are infectious agents made only of misfolded proteins without any nucleic acid, causing disease by converting normal host proteins into the abnormal form. Viroids are small, circular RNA molecules without a protein coat that infect plants, with RNA serving as their genetic material. A virion is the complete virus particle, always containing nucleic acid (DNA or RNA) within a protein coat and sometimes an envelope. Non-enveloped viruses lack a lipid envelope but still carry nucleic acid as genetic material inside a protein capsid. Unlike prions, which do not use nucleic acids, viroids, virions, and non-enveloped viruses all depend on nucleic acids.
