**Core Concept**
Postoperative jaundice is a complication that can occur after surgery, often due to a temporary blockage of bile flow. This condition is usually caused by the use of certain medications or anesthetic agents that can affect liver function or bile ducts.

**Why the Correct Answer is Right**
The correct answer is related to the mechanism of action of a specific anesthetic agent. Succinylcholine, a depolarizing muscle relaxant, can cause postoperative jaundice by inducing transient biliary obstruction and increasing bile duct pressure. This is due to the release of histamine and other substances that can cause contraction of the sphincter of Oddi, leading to a temporary blockage of bile flow.

**Why Each Wrong Option is Incorrect**
* **Option A:** This option is incorrect because it does not specifically relate to the cause of postoperative jaundice. While certain antibiotics can cause liver damage, they are not the primary cause of postoperative jaundice.
* **Option B:** This option is incorrect because it does not accurately describe the mechanism of action of the correct answer. Although certain anesthetic agents can cause liver damage, succinylcholine is the specific agent that is most commonly associated with postoperative jaundice.
* **Option C:** This option is incorrect because it does not specifically relate to the cause of postoperative jaundice. While certain medications can cause liver damage, they are not the primary cause of postoperative jaundice.

**Clinical Pearl / High-Yield Fact**
To remember the cause of postoperative jaundice, recall that succinylcholine can cause a transient blockage of bile flow by inducing contraction of the sphincter of Oddi. This is a classic exam trap that can be avoided by remembering the mechanism of action of this anesthetic agent.

**Correct Answer:** C. Succinylcholine.
