Ans. (B) All women who could become pregnant(Ref: Nelson 19th/e p2001)"The U.S. Public Health Service has recommended that all women of childbearing age and who are capable of becoming pregnant take 0.4 mg of folic acid daily. If, however, a pregnancy is planned in high-risk women (previously affected child), supplementation should be started with 4 mg (= 4000 microgram) of folic acid daily, beginning 1 month before the time of the planned conception."
