A. Less secretion of thyroxine in adult
B. Excessive secretion of thyroxine in adult
C. Excessive secretion of calcitonin
D. Less secretion of thyroxine right from birth

Answer 1

Hint: The swelling around the eyes is seen in Thyroid Eye Disease. In this condition the fat deposits in the face and the eyes.

Step by step answer:If an individual has swelling around the eyes and large popping eyeballs. These symptoms are seen in Thyroid Eye disease (TED). Thyroid eye disease is a condition of the Exophthalmic Goiter. It is a genetic disorder. It occurs due to the hypersecretion of the thyroxine hormone from the thyroid gland. This is because TSH mimics its role to stimulate the forceful secretion of the thyroid. It destroys the immunoglobulin. In this condition the fat deposits in the face and the eyes. This causes the swelling in the follicle glands, causing their enlargement. Due to this, the face looks terrible and the eyes protrude and bulge out. This condition is known as Exophthalmos. The continuous enlargement of the glands is known as Grave’s disease.
Also, the formation of the fat nodules in the gland is known as the Plummer’s disease. Both the Grave’s disease and the Plummer’s disease are the symptoms of the Exophthalmic Goiter. It is an autoimmune disease.
Thus, the swelling around the eyes and large popping eyeballs are observed in an individual who has the excessive secretion of thyroxine.
Hence, the correct answer is option (B)

Note: Thyroxine is a common name for Tetraiodothyronine or ${{T}_{4}}$. It is found $80%$ in the Thyroid hormone. Thyroxine has to first convert into Triiodothyronine and then only it can produce its chemical effects. This process of conversion occurs in the Liver.
