**Core Concept**
Iodine is an essential micronutrient required for the synthesis of thyroid hormones (T3 and T4). The thyroid gland absorbs iodine from the bloodstream and incorporates it into thyroglobulin, which is then cleaved to produce T3 and T4. Iodine deficiency can lead to hypothyroidism, goiter, and cretinism.

**Why the Correct Answer is Right**
The minimum daily intake of iodide is crucial for maintaining thyroid function. The World Health Organization recommends a daily intake of 150 mcg for adults. This amount is sufficient to maintain normal thyroid hormone production and prevent iodine deficiency disorders. The thyroid gland has a high affinity for iodine, and the recommended daily intake is essential for optimal thyroid function.

**Why Each Wrong Option is Incorrect**
**Option A:** This option is incorrect because the recommended daily intake of iodide is higher than the minimum required to prevent iodine deficiency disorders. While this amount may be sufficient for some individuals, it is not the minimum recommended daily intake.
**Option B:** This option is incorrect because the recommended daily intake of iodide is lower than the minimum required to prevent iodine deficiency disorders. This amount may be insufficient for individuals with increased thyroid hormone requirements, such as pregnant women or those with thyroid disease.
**Option C:** This option is incorrect because it is not a commonly recognized or recommended daily intake of iodide. While some individuals may require higher or lower intakes based on their specific needs, this option does not align with established guidelines.

**Clinical Pearl / High-Yield Fact**
Iodine deficiency can lead to a range of clinical manifestations, including hypothyroidism, goiter, and cretinism. It is essential to maintain adequate iodine intake, particularly in regions with iodine-deficient soil or where iodized salt is not widely available.

**Correct Answer: D. 150 mcg**
