Answer: 2. They have free RNA without protein coat.

Viroids are free RNA molecules without a protein coat, and are smaller than viruses. They were discovered by T.O. Diener and cause potato spindle tuber disease.

Viruses have a protein coat, and viroids do not have DNA, so options 1, 3 and 4 are wrong.
