Hepatitis can be classified into several types commonly labeled with letters. Which statement is true?

• A. Types A through G
• B. Types X through Z
• C. Types 1 through 5
• D. Types Alpha to Omega

Answer: (A)

Naming hepatitis viruses with letters is the concept being tested. In medical naming, hepatitis types are designated by letter labels, commonly extending from A to G. The well-established types include A, B, C, D, and E, with F and G appearing in some classifications as additional types, though not all sources treat them as universally recognized. The other naming schemes—X through Z, 1 through 5, or Alpha to Omega—aren’t used to categorize hepatitis viruses. So the statement that hepatitis types are labeled A to G is the true one.
