## Core Concept
The question pertains to the nutritional fortification of Dalda, a commonly consumed food item, particularly in regions where micronutrient deficiencies are prevalent. Fortification of foods with essential vitamins and minerals like Vitamin A and Vitamin D is a public health strategy to prevent deficiencies. The specific doses of these vitamins added to Dalda are critical for ensuring the desired nutritional benefit without causing toxicity.

## Why the Correct Answer is Right
The correct answer specifies that Dalda is fortified with 1000 IU of Vitamin A and 200 IU of Vitamin D per 100 grams. This fortification level is designed to enhance the nutritional value of Dalda, addressing potential deficiencies in Vitamin A and Vitamin D in the population consuming it. Vitamin A is crucial for vision, immune function, and skin health, while Vitamin D is essential for bone health and immune function. The specified doses aim to contribute significantly to the daily recommended intake of these vitamins.

## Why Each Wrong Option is Incorrect
- **Option A:** This option suggests a different dose, which may not align with standard fortification practices or could be too low to effectively address deficiencies.
- **Option B:** Similarly, this option presents an alternative dose that might not be optimal or could be based on outdated guidelines.
- **Option D:** This option provides another set of doses that could be incorrect based on current nutritional guidelines or fortification standards.

## Clinical Pearl / High-Yield Fact
A key point to remember is that food fortification is a strategy used to prevent micronutrient deficiencies. For Vitamin A and Vitamin D, the goal is to support vision, immune function, bone health, and overall well-being. Knowing the specific fortification levels in commonly consumed foods like Dalda can help in understanding how dietary sources contribute to daily vitamin intake.

## Correct Answer Line
**Correct Answer: C. 1000 IU of Vitamin A and 200 IU of Vitamin D.**
