Viroids are infectious pathogens that affect only plants, therefore are also called as the plant pathogens. Structurally, viroids are smaller than viruses and possess circular strands of ribonucleic acids (RNA’s) with no protein coating. These entities hijack the cellular machinery present in plant cells to replicate new copies of itself. It primarily affects all forms of higher plants.
Viroid were discovered by Dr. Theodor.O. Diener in the year 1971. It was found to be a free RNA; it lacked the protein coat that is found in viruses, hence it is named as viroid. It was first examined in the potato spindle tuber viroid that caused a huge loss to the potato industry.
So, the correct answer is "option B".
