**Core Concept:** The USHA (Universal Salt Iodization Programme) is a public health initiative aimed at preventing iodine deficiency disorders (IDDs) in the population by adding iodine to table salt.

**Why the Correct Answer is Right:** The correct answer is the one that refers to the target population addressed by the Universal Salt Iodization Programme. Iodine deficiency disorders are primarily caused by insufficient intake of iodine in the diet, which can be corrected by adding iodine to commonly consumed items like table salt.

**Why Each Wrong Option is Incorrect:**
A. Incorrect as it refers to a specific population, which is not the focus of the USHA initiative.
B. Incorrect as it refers to a specific condition rather than the target population of the USHA programme.
C. Incorrect because it refers to a specific location (India) rather than the broader population addressed by the USHA initiative.
D. Incorrect as it refers to a specific group (people with celiac disease), which is not the primary focus of the USHA programme.

**Clinical Pearl / High-Yield Fact:** Iodine deficiency is a significant global health concern affecting approximately 1.1 billion people worldwide. Preventing IDDs through initiatives like the Universal Salt Iodization Programme helps reduce the prevalence of iodine deficiency disorders and improves cognitive function, fertility, and overall health outcomes in the affected population.
