**Core Concept**
Obstructive jaundice occurs when there is a blockage in the bile ducts, preventing bilirubin from leaving the liver. This condition can lead to a buildup of conjugated bilirubin in the blood. The underlying principle being tested is the management of obstructive jaundice.

**Why the Correct Answer is Right**
Since the correct answer is not provided, let's discuss the general approach to obstructive jaundice. In this condition, the goal is to relieve the obstruction and restore bile flow. This can be achieved through various methods such as endoscopic retrograde cholangiopancreatography (ERCP), percutaneous transhepatic cholangiography (PTC), or surgical intervention.

**Why Each Wrong Option is Incorrect**
**Option A:** Without the specific details of option A, it's challenging to provide a precise explanation. However, any option that does not address the relief of the obstruction would be incorrect.
**Option B:** Similarly, without specifics, any option that does not involve a procedure to restore bile flow would be wrong.
**Option C:** This option would be incorrect if it suggested a treatment that does not address the underlying cause of the obstruction.
**Option D:** Any option that recommends a treatment that worsens the condition or does not alleviate the obstruction would be incorrect.

**Clinical Pearl / High-Yield Fact**
A key point to remember in obstructive jaundice is that it's crucial to relieve the obstruction promptly to prevent complications such as cholangitis.

**Correct Answer:** Correct Answer: D. ERCP can be done in obstructive jaundice.
