**Core Concept**
The **World Health Organization (WHO)** recommends the use of **Oral Rehydration Solution (ORS)** with reduced osmolality to treat dehydration, especially in children. This formulation is designed to balance **electrolytes** and **glucose** to facilitate optimal **intestinal absorption**.

**Why the Correct Answer is Right**
The reduced osmolality ORS has a lower concentration of **sodium** and **glucose**, which reduces the risk of **osmotic diarrhea**. This formulation is based on the principle that **cotransport of sodium and glucose** enhances **water absorption** in the small intestine, mediated by the **SGLT1 receptor**.

**Why Each Wrong Option is Incorrect**
**Option A:** Incorrect because reduced osmolality ORS is indeed recommended by the WHO.
**Option B:** Incorrect as it does contain **potassium**, essential for replacing losses.
**Option C:** Incorrect because it is designed to reduce **stool output**.

**Clinical Pearl / High-Yield Fact**
The key advantage of reduced osmolality ORS is its ability to decrease **vomiting** and **diarrhea** while effectively rehydrating patients.

**Correct Answer:** D. It does not contain enough sodium to be used for the treatment of cholera.
