Answer 1

The correct option is D All of the above

The follicular cells of the thyroid gland are responsible for the synthesis of the thyroid hormones triiodothyronine ($T_3$) and tetraiodothyronine ($T_4$).

The $\alpha$-cells and $\beta$-cells of the endocrine part of the pancreas secrete glucagon and insulin, respectively.
