Correct option is B. Adenovirus - Cause of respiratory disease. Adenoviruses are a group of viruses that typically cause respiratory illnesses, such as a common cold, conjunctivitis (infection in the eye), bronchitis, or pneumonia. In children, adenoviruses usually cause infections in the respiratory tract and intestinal tract. The Potato spindle tuber viroid was the first viroid to be identified. It is a small, single-stranded circular RNA molecule, infecting potatoes and tomatoes. Tobacco mosaic disease is caused by the Tobacco mosaic virus, a single-stranded RNA virus. It infects a wide range of plants, especially tobacco and other members of the family Solanaceae. The infection causes characteristic patterns, such as "mosaic"-like mottling and discoloration on the leaves. A prion is a type of protein that can trigger normal proteins in the brain to fold abnormally, leading to diseases like Alzheimer's disease and Creutzfeldt-Jakob disease (CJD).
