Deficiency of which hormone in the body causes 'Goitre'?

Thyroxine

The correct answer is Option (1)- Thyroxine

The deficiency of the hormone Thyroxine causes 'Goitre.'

Explanation:

• Goitre is an enlargement of the thyroid gland, located in the neck.
• Thyroxine, also known as T4, is a hormone produced by the thyroid gland. It plays a crucial role in regulating the body's metabolism and energy production.
• In conditions where there is a deficiency of iodine, an essential component for the synthesis of thyroid hormones, the thyroid gland enlarges in an attempt to produce more hormones.
• The lack of iodine affects the production of thyroxine, leading to an imbalance in thyroid function and resulting in the development of goitre.

Therefore, the correct answer is Thyroxine.
