The correct option is C Thyroxine
Thyroxine
is known as thyroid hormone as it is synthesized in thyroid gland. This hormone
is released under the influence of TSH, released by anterior pituitary. Iodine is
essential for the normal rate of hormone synthesis in thyroid. Thyroxine hormone
controls growth, mental faculties and tissue differentiation. It controls the
metabolism of proteins, fats and carbohydrates and hence regulates the growth
of the body tissues. These hormones play an important role in the regulation of
the basal metabolic rate (BMR).
