**Core Concept**
Acute hepatitis refers to the inflammation of the liver, which can be caused by various factors such as viral infections (e.g., hepatitis A, B, C, D, E), toxins, medications, and autoimmune disorders. This condition can lead to liver dysfunction, jaundice, and potentially severe complications.

**Why the Correct Answer is Right**
During acute hepatitis, the liver's synthetic functions are impaired, leading to decreased production of coagulation factors, particularly prothrombin. This results in an increased risk of bleeding and a prolonged prothrombin time (PT). The liver's detoxification functions are also compromised, contributing to the accumulation of bilirubin and the development of jaundice.

**Why Each Wrong Option is Incorrect**
**Option A:** This option is incorrect because it does not accurately describe a characteristic of acute hepatitis.
**Option B:** This option is incorrect because it is not a typical feature of acute hepatitis.
**Option C:** This option is incorrect because it is not a direct consequence of acute hepatitis.

**Clinical Pearl / High-Yield Fact**
In patients with acute hepatitis, a prolonged PT and decreased platelet count are indicative of significant liver dysfunction and an increased risk of bleeding.

**Correct Answer:** D
