Answer

To determine which one of the following is a viral disease of poultry, we will analyze each option provided:

1. **Choriza**: This condition is primarily related to respiratory issues in birds, often caused by irritation in the nasal passages leading to mucus production. While it can be associated with viral infections, it is not specifically classified as a viral disease in poultry. Therefore, this option is incorrect.

2. **Newcastle Disease**: This is a well-known viral disease that affects poultry, particularly chickens. It impacts both the respiratory and nervous systems of birds. Symptoms include respiratory distress and a drop in egg production. This disease is caused by the Newcastle disease virus, making this option a correct answer.

3. **Ranikhet**: This is another name for Newcastle disease. Therefore, it is also a viral disease affecting poultry. This option is also correct.

4. **Salmonellosis**: This disease is caused by bacteria, specifically Salmonella species, and is not a viral disease. Therefore, this option is incorrect.

**Final Answer**: The correct answers are **Newcastle Disease** and **Ranikhet**, both of which are viral diseases of poultry.
