Answer 1

Ranikhet disease is also known as Newcastle Disease. The causative agent of the disease is a virus called Newcastle Disease Virus or NDV. This disease is prevalent in birds. The disease can cause 50 to 100 percent mortality in birds.

Complete answer:
The Ranikhet Disease or Newcastle Disease is a fatal pathogen for birds. This is caused by an RNA virus called Newcastle Disease Virus. It is prevalent worldwide and affects domesticated and wild birds. Poultry, turkey, parrots, geese, pheasants are all affected by the virus.
Therefore, option (c) is correct.

Additional Information:
Ranikhet Disease is caused by a family of viruses known as Paramyxovirus. This virus is a single strand RNA genome virus and is known to cause lower respiratory tract diseases. This disease is prevalent in Asia, Africa, some North and South American countries.
The Ranikhet or Newcastle Disease occurs mainly in birds like domesticated fowl, ducks, geese, turkey. Clinical symptoms are diarrhea, acute respiratory disease. If the infection is acute, the nervous symptoms like twisted head and depression is demonstrated. The birds can die suddenly.
The transmission occurs by exposure to fecal matter of infected birds, direct contact with infected birds, consumption of contaminated food or drink. The capacity of the virus to infect animals can be very high or low. The disease spreads in birds that are confined in small areas.
The virus can survive in the feathers of birds, manure, given the warm environment, for many days. However, UV rays of the sun, and dehydration can destroy the virus. Methods of prevention include vaccination against the Newcastle Disease Virus and proper quarantining measures. Some countries like Australia have made the vaccination against this virus mandatory for birds used for commercial purposes.

Note: The Ranikhet Disease is a fatal disease of birds caused due to a family of paramyxoviruses. The mortality rate of this disease is around 90 percent in birds. Human transmission of the virus is possible if meat or products of infected animals are consumed. However, humans are known to have mild symptoms like influenza and conjunctivitis.
