Options
- AA - 3, B - 2, C - 1, D - 4
- BA - 4, B - 2, C - 1, D - 3
- CA - 2, B - 1, C - 4, D - 3
- DA - 1, B - 3, C - 4, D - 2
Correct answer
C. A - 2, B - 1, C - 4, D - 3
Step-by-step solution
A - 2: Plant viruses generally have single-stranded RNA and can cause symptoms such as mosaic formation. B - 1: Bacteriophages are typically double-stranded DNA viruses that infect bacteria. C - 4: Animal viruses can have single or double-stranded RNA or double-stranded DNA, causing various diseases in animals. D - 3: Viruses that cause diseases like smallpox and AIDS can be crystallized and have a protein coat, reflecting their structural characteristics.
