The correct answer is (B) Paramyxovirus.
Ranikhet disease (also known as Newcastle disease) is a highly contagious viral disease that affects poultry, caused by the Paramyxovirus of the genus Avulavirus. This virus affects the respiratory, nervous, and digestive systems of birds, leading to high mortality rates in infected flocks.
Let's briefly go over the other options:
(A) Herpesvirus: Herpesviruses cause different types of diseases in animals, but they are not responsible for Ranikhet disease.
(C) Avipoxvirus: Avipoxvirus causes pox diseases in birds, such as fowlpox, but it is not the cause of Ranikhet disease.
(D) H1N1 influenza virus: The H1N1 influenza virus is a strain of the influenza virus that affects humans and some animals, but it is not related to Ranikhet disease in poultry.
Thus, the correct cause of Ranikhet disease is (B) Paramyxovirus.
Ranikhet disease, also known as Newcastle disease, is caused by a virus belonging to the Paramyxovirus family. It affects poultry and is characterized by respiratory distress and neurological symptoms.
