The correct answer is C. Thyroid.
Cretinism is a condition that occurs when the thyroid gland does not produce enough thyroid hormone. This can happen before birth, during childhood, or in adulthood. The thyroid gland is a small, butterfly-shaped gland located in the neck. It produces hormones that are essential for growth and development.
If a child is born with cretinism, they may have a number of problems, including:
- Slow growth
- Mental retardation
- Deafness
- Seizures
- Heart problems
If cretinism is not treated, it can lead to serious health problems, including death. Treatment for cretinism involves taking thyroid hormone replacement medication. This medication can help to improve growth, development, and mental function.
The other options are incorrect because they are not glands that produce thyroid hormone. The thymus is a gland located in the chest that helps the body fight infection. The parathyroid glands are four small glands located in the neck that help to regulate calcium levels in the blood. The adrenal glands are two small glands located on top of the kidneys that produce hormones that help to regulate the body’s response to stress.
