**Core Concept**
Savlon is an antiseptic solution commonly used in medical settings for wound care and skin disinfection. It contains a combination of ingredients that provide antimicrobial and antiseptic properties.

**Why the Correct Answer is Right**
Savlon contains 2% chlorhexidine gluconate and 1% iodine. Chlorhexidine gluconate is a broad-spectrum antimicrobial agent that disrupts bacterial cell membranes, ultimately leading to cell death. Iodine, on the other hand, has a broad spectrum of antimicrobial activity and is effective against a wide range of bacteria, viruses, and fungi. The combination of these two ingredients makes Savlon an effective antiseptic solution for wound care and skin disinfection.

**Why Each Wrong Option is Incorrect**
**Option A:** This option is incorrect because it does not specify the correct ingredients in Savlon.
**Option B:** This option is incorrect because it contains a mixture of ingredients that are not typically found in Savlon.
**Option C:** This option is incorrect because it lists a single ingredient, whereas Savlon contains a combination of chlorhexidine gluconate and iodine.

**Clinical Pearl / High-Yield Fact**
When using antiseptic solutions like Savlon, it's essential to note that chlorhexidine gluconate can cause skin irritation and allergic reactions in some individuals. Therefore, it's crucial to perform a patch test before applying Savlon to a large area.

**Correct Answer: D. 2% chlorhexidine gluconate and 1% iodine**
