C. Hypoparathyroidism, parathyroid, goitre
D. Hyperthyroidism, thyroid, acromegaly

Answer

### Step-by-Step Solution:

1. **Understanding Iodine's Role**: Iodine is an essential nutrient required for the synthesis of thyroid hormones, particularly thyroxine (T4). The thyroid gland utilizes iodine to produce these hormones.

2. **Identifying the Condition Caused by Iodine Deficiency**: When there is a deficiency of iodine in the diet, the thyroid gland cannot produce enough thyroid hormones. This condition is known as hypothyroidism.

3. **Effects of Hypothyroidism**: The lack of sufficient thyroid hormones leads to various physiological changes, one of which is the enlargement of the thyroid gland. This enlargement occurs as the gland tries to compensate for the low hormone levels.

4. **Naming the Condition**: The enlargement of the thyroid gland due to iodine deficiency is commonly referred to as "goiter." There are different types of goiter, including simple goiter and endemic goiter, depending on the context and severity.

5. **Final Answer**: Therefore, the complete answer to the question is:
- Iodine deficiency in our diet results in **hypothyroidism** and enlargement of the **thyroid** gland, commonly called **goiter**.
