Which of the following organisms causes the disease hepatitis?

Correct option is C

The correct answer is (c)  Virus
Explanation: •  Hepatitis is an inflammatory condition of the liver. • It is most commonly caused by a group of specific  viruses, identified as Hepatitis A, B, C, D, and E viruses. • Each virus type has different modes of transmission and severity of illness.
Information Booster: •  Hepatitis B and C are the most common causes of chronic liver disease, cirrhosis, and liver cancer globally. • There are effective vaccines available for Hepatitis A and B.
Additional Knowledge: (a) Bacteria .: • While some bacterial infections can affect the liver secondarily (e.g., leptospirosis), the primary cause of the disease "hepatitis" (as a viral condition) is not bacteria.
(b) Protozoa .: • Protozoan infections (e.g., amoebiasis) can affect the liver and cause abscesses, but not the specific disease "hepatitis".
(d) Fungus .: • Fungal infections of the liver are rare, typically affecting immunocompromised individuals, and are not the primary cause of hepatitis.
