A
T3 and T4
B

C
ADH
D

Explanation: 

Detailed explanation-1: -Thyroid cells are the only cells in the body which can absorb iodine. These cells combine iodine and the amino acid tyrosine to make T3 and T4. T3 and T4 are then released into the blood stream and are transported throughout the body where they control metabolism (conversion of oxygen and calories to energy).

Detailed explanation-2: -The thyroid regulates your metabolism. The two main thyroid hormones are T3 and T4. Thyroid disorders are common, and they include goiters, hyperthyroidism, and hypothyroidism.

Detailed explanation-3: -TSH, in turn, stimulates thyroid follicular cells to release thyroxine or T4 (80%), and triiodothyronine or T3 (20%). Somatostatin, on the other hand, is another hormone produced by the hypothalamus that inhibits the release of TSH from the anterior pituitary.
