Answer:
The answer is "C. proteins"
Step-by-step explanation:
Viroids are the smallest infectious pathogens. They resemble a virus and cause diseases to plants. This pathogen consists of a single strand of Ribonucleic Acid (RMA) but are different from a virus since it does not have a protein coat that other viruses have. They consist of only nucleic acids. Other than this, Viroids also RMA that have catalytic capabilities which allows them to have self-cleaving properties.
