Options

A. `{:("Plant disease", , "Animal disease"), ("Leaf rolling",-, "Mumps):}`
B. `{:("Plant disease", ,"Animal disease"), ("Yellowing", - , "Herpes"):}`
C. `{:("Plant disease", , "Animal disease"), ("Vein clearing", - ,"Influenza"):}`
D. `{:("Plant disease", , "Animal disease"), ("Damping off", - , "Diptheria"):}`

Answer

To solve the question of selecting the incorrect option with respect to viral diseases in both plants and animals, we will analyze each option provided in the question.

### Step-by-Step Solution:

1. **Identify the Options**: We need to look at the options given for viral diseases in plants and animals. Each option consists of a plant disease and an animal disease.

2. **Analyze Plant Diseases**:
- **Leaf Rolling**: This is a viral disease in plants, often caused by viruses like Cucumber Mosaic Virus (CMV).
- **Vein Clearing**: This is also a viral disease in plants, indicating the presence of viral infections.
- **Dumping Off Disease**: This is caused by a fungus, not a virus. This indicates that this option is incorrect.

3. **Analyze Animal Diseases**:
- **Mumps**: This is a viral disease caused by the mumps virus.
- **Herpes**: This is also a viral disease caused by the Herpes Simplex Virus.
- **Influenza**: This is a viral infection caused by the influenza virus.
- **Diphtheria**: This is a bacterial infection, not a viral disease.

4. **Identify the Incorrect Option**:
- The fourth option is incorrect because it lists "Dumping Off Disease" as a viral disease in plants (which is false) and "Diphtheria" as a viral disease in animals (which is also false). Both are not caused by viruses.

5. **Conclusion**: The correct answer to the question is the fourth option, as it incorrectly identifies both diseases.

### Final Answer:
The incorrect option with respect to viral diseases in both plants and animals is the fourth option.
