Select the correct statement -a)Viriods are similar in size to viruses...
The correct statement is D: None of these.

- Prions vs. Viruses: Prions are not smaller in size than viruses but are similar in size to them
- Lichens and Proto-cooperation: Lichens represent a symbiotic relationship between fungi and algae, showcasing mutualism rather than proto-cooperation.
Therefore, none of the statements A, B, or C are accurate.

Select the correct statement -a)Viriods are similar in size to viruses...
Explanation:
Viriods vs. Prions:
- Viriods are small infectious pathogens that are similar in size to viruses, consisting of only RNA without a protein coat.
- Prions, on the other hand, are smaller than viruses and viriods. They are infectious proteins that can cause misfolding of normal proteins in the brain, leading to neurodegenerative diseases.
Lichens and Proto-cooperation:
- Lichens are a symbiotic relationship between a fungus and a photosynthetic partner (algae or cyanobacteria).
- This relationship is an example of proto-cooperation, where both partners benefit from the association but are not completely dependent on each other for survival.
Therefore, option 'D' - "None of these" is the correct statement as none of the statements provided are accurate.
