**Core Concept**
Lugol's Iodine is a type of antiseptic solution that has been used for various medical and surgical applications. It is a mixture of elemental iodine and potassium iodide in water, which provides a broad spectrum of antimicrobial activity.

**Why the Correct Answer is Right**
Lugol's Iodine contains a combination of 5% elemental iodine (I2) and 10% potassium iodide (KI) in water. The presence of potassium iodide helps to stabilize the elemental iodine, allowing it to maintain its antimicrobial properties. This solution is effective against a wide range of microorganisms, including bacteria, fungi, and viruses.

**Why Each Wrong Option is Incorrect**
**Option A:** Iodophor - Iodophors are a type of iodine-based antiseptic solution, but they are not the same as Lugol's Iodine. Iodophors typically contain a complex of iodine and a nonionic surfactant.
**Option B:** Povidone Iodine - Povidone iodine is another type of iodine-based antiseptic solution, but it is not Lugol's Iodine. Povidone iodine is a complex of iodine and polyvinylpyrrolidone (PVP).
**Option C:** Betadine - Betadine is a brand name for povidone iodine, which is not the same as Lugol's Iodine.

**Clinical Pearl / High-Yield Fact**
Lugol's Iodine is commonly used as a skin disinfectant before surgical procedures, and it is also effective against fungal and bacterial infections of the skin and mucous membranes.

**Correct Answer: C. Potassium Iodide and Elemental Iodine.**
