Which of the following can he used in pregnancy?

Ans. d. Propylthiouracil Propylthiouracil is the drug of choice for hyperthyroidism during pregnancy."ACE inhibitors inhibit the conversion of angiotensin-I to the potent vasoconstrictor angiotensin-II. They can cause severe fetal malformations that include hypocalvaria when given in the second and third trimesters. Because of this, they are not recommended during pregnancy. Angiotensin-receptor blockers act in a similar manner, but instead of blocking the production of angiotensin-II, they inhibit binding to its receptor. They are presumed to have the same fetal effects as ACE inhibitors and are also contraindicated.
