**Core Concept**
The Wolf-Chaikoff effect is a physiological phenomenon where the administration of a large dose of iodine temporarily inhibits the synthesis of thyroid hormones in the thyroid gland.

**Why the Correct Answer is Right**
The mechanism behind the Wolf-Chaikoff effect involves the inhibition of the enzyme thyroperoxidase, which is necessary for the conversion of iodide to iodine and the subsequent incorporation of iodine into thyroxine (T4) and triiodothyronine (T3). When a large dose of iodine is administered, it accumulates in the thyroid gland and inhibits the activity of thyroperoxidase, leading to a decrease in thyroid hormone production.

**Why Each Wrong Option is Incorrect**

**Option A:** This option is incorrect because the inhibition of thyroperoxidase is a specific and well-characterized mechanism of the Wolf-Chaikoff effect, and not a general decrease in thyroid function.
**Option B:** This option is incorrect because the administration of a large dose of iodine does not stimulate the release of pre-formed thyroid hormones from the thyroid gland.
**Option C:** This option is incorrect because the inhibition of thyroid hormone synthesis is a direct result of the accumulation of iodine in the thyroid gland, and not a result of a decrease in thyroid-stimulating hormone (TSH) secretion.

**Clinical Pearl / High-Yield Fact**
The Wolf-Chaikoff effect is an important consideration in patients undergoing thyroid surgery or radioactive iodine ablation, as it can lead to a temporary decrease in thyroid hormone production and potential hypothyroidism.

**Correct Answer:** D.
