**Core Concept**
Hepatitis A is a self-limiting liver disease caused by the hepatitis A virus (HAV), primarily transmitted through the fecal-oral route. It affects the liver's parenchymal cells, leading to inflammation and damage.

**Why the Correct Answer is Right**
Hepatitis A virus (HAV) primarily infects the hepatocytes, causing a mild to moderate inflammatory response. The virus is highly contagious and can be spread through contaminated food, water, or direct contact with an infected person. The incubation period ranges from 15 to 50 days, during which the individual is asymptomatic but highly infectious.

**Why Each Wrong Option is Incorrect**
**Option A:** This statement is not true about hepatitis A. Hepatitis B, not A, is transmitted through bodily fluids like blood, semen, and other bodily secretions. Hepatitis A is primarily spread through the fecal-oral route.
**Option B:** This statement is true about hepatitis A. Hepatitis A is indeed a self-limiting disease, meaning it resolves on its own without treatment. However, this option is not the correct answer as all the options are supposed to be true about hepatitis A.
**Option D:** This statement is not true about hepatitis A. Hepatitis B, not A, is associated with an increased risk of developing hepatocellular carcinoma (liver cancer) in the long term.

**Clinical Pearl / High-Yield Fact**
The hepatitis A vaccine is a highly effective measure against the disease, providing long-term immunity against HAV. It is recommended for individuals traveling to high-risk areas, healthcare workers, and those with pre-existing liver disease.

**Correct Answer:** A.
