Explanation:

The correct answer is option C: Thyroid hormone.

Hyposecretion of Thyroid Hormone:

When the thyroid gland does not produce enough thyroid hormone, it is known as hypothyroidism. This condition can lead to various symptoms and complications, including stunted growth and mental retardation.

Thyroid Hormone and Growth:

Thyroid hormone plays a crucial role in regulating growth and development, particularly during childhood. It stimulates the production of growth hormone, which is responsible for the growth and development of bones, muscles, and other tissues. Thyroid hormone also influences the metabolism of proteins, carbohydrates, and fats, which are essential for normal growth.

Effects of Hypothyroidism on Growth:

When there is a hyposecretion of thyroid hormone, the production of growth hormone is also affected. This can result in a condition called cretinism, characterized by stunted growth and mental retardation.

Stunted Growth:

The deficiency of thyroid hormone affects the growth plates in the long bones, which are responsible for bone growth. Without adequate thyroid hormone, the growth plates close prematurely, leading to reduced bone length and overall stunted growth.

Mental Retardation:

Thyroid hormone is also important for the development and functioning of the brain. Inadequate levels of thyroid hormone can impair brain development, leading to mental retardation. This can result in cognitive and intellectual disabilities, affecting the individual's overall cognitive abilities, learning, and behavior.

Conclusion:

In summary, the hyposecretion of thyroid hormone can have significant effects on growth and development. Stunted growth and mental retardation are common consequences of hypothyroidism. Therefore, the correct answer is option C: Thyroid hormone.
