D. Myxoedema

Answer

### Step-by-Step Solution:

1. **Understanding Hypothyroidism**: Hypothyroidism is a condition characterized by insufficient production of thyroid hormones (T3 and T4) by the thyroid gland. This can lead to various metabolic issues in the body.

2. **Identifying the Thyroid Gland's Role**: The thyroid gland is the largest endocrine gland located in the neck region. It produces hormones that regulate the body's basal metabolic rate, which affects how the body uses energy.

3. **Consequences of Low Hormone Levels**: In adults, low levels of thyroid hormones can lead to several health issues. The most common consequences include:
- **Obesity**: Due to a slowed metabolism, individuals may gain weight.
- **Diabetes**: Hypothyroidism can affect insulin sensitivity, leading to higher blood sugar levels.
- **Myxoedema**: This is a severe form of hypothyroidism in adults, characterized by swelling of the skin and underlying tissues.
- **Cretinism**: This condition is specifically related to hypothyroidism in newborns and is not applicable to adults.

4. **Conclusion**: The primary causes of hypothyroidism in adults include obesity, diabetes, and myxoedema. Cretinism is not relevant in this context as it pertains to infants.

5. **Final Answer**: The correct causes of hypothyroidism in adults are obesity, diabetes, and myxoedema.
