Best answer

The correct option is: (a) single stranded RNA not enclosed by protein coat

Explanation:

The term viroid was introduced by 'Diener' (1971). Viroids are a group of pathogens of some higher plants that are smaller and simpler than any of the known viruses. They consist of only a naked strand of nucleic acid without a protein coat. The nucleic acid of all viroids discovered so far has been shown to consist of single stranded linear or circular RNA.
