Which condition has the lowest elevation of transaminases among the listed options?

Chronic hepatitis is characterized by ongoing inflammation of the liver that lasts for at least six months. In many cases, patients with chronic hepatitis have milder elevations of liver enzymes, such as transaminases (AST and ALT), compared to acute conditions. This is due to the nature of chronic liver inflammation where the injury is more gradual, and the overall liver function may remain relatively preserved for long periods.

In contrast, acute hepatitis typically results in significantly elevated transaminase levels as the liver undergoes rapid and severe inflammation. Obstructive jaundice can also lead to elevated transaminases due to bile duct obstruction leading to liver damage and cholestasis. Hepatic cancer may lead to variable enzyme elevation depending on the tumor's characteristics and the underlying liver condition, but it often does not result in the lowest levels compared to chronic hepatitis.

Therefore, in the context of the listed conditions, chronic hepatitis will generally exhibit the lowest elevation of transaminases, making it the correct answer.
