(D) Antithyroid substances are compounds that interfere with the synthesis,release,or action of thyroid hormones. $1$. Thiocyanate ions inhibit the uptake of iodide by the thyroid gland. $2$.

High concentrations of inorganic iodides (Wolff-Chaikoff effect) can temporarily inhibit the synthesis and release of thyroid hormones. Therefore,all the listed substances are considered antithyroid substances.
