**Core Concept**
Hepatitis viruses are a group of RNA viruses that infect the liver and cause inflammation. They can be transmitted through various routes, including blood, feces, and sexual contact. Understanding the transmission modes of different hepatitis viruses is crucial for prevention and treatment.

**Why the Correct Answer is Right**
The correct answer is **D.**, but since it is not provided, I will assume it is a placeholder. Normally, we would identify a hepatitis virus that is not primarily transmitted through blood. For example, Hepatitis E virus (HEV) is primarily transmitted through the fecal-oral route, often through contaminated water or food. In contrast, Hepatitis A virus (HAV) is also primarily transmitted through the fecal-oral route.

**Clinical Pearl / High-Yield Fact**
Hepatitis viruses can be divided into two main categories: hepatotropic (directly infecting the liver) and non-hepatotropic (indirectly affecting the liver). Understanding this distinction is crucial for diagnosis and treatment.
