Which of the following is true about folate?

Question

BlackTom AI · Accepted Answer

Question at hand asks about folate and its true statements. 
Option a) 'Folate helps prevent NTDs' is a well-established fact: adequate folate status around conception and early pregnancy reduces the risk of neural tube defects in the developing fetus. This makes the statement accurate. 
Option b) 'Folate deficiency causes microcytic anemia' is incorrect. Folate deficiency typically leads to macrocytic (megaloblastic) anemia because DNA synthesis is impaired, causing enlarged red blood cells; microcytic anemia is more characteristic of iron deficiency or certain thalassemias. 
Option d) 'Folate deficiency causes Wernicke-Korsakoff syndrome' is also incorrect. Wernicke-Korsakoff is most closely linked to thiamine (vitamin B1) deficiency, not folate deficiency, so this statement misattributes a neurological syndrome to the wrong nutrient. 
Option d) ' a) and b)' as a combined choice asserts both a) and b) are true. Since b) is false, this combined option is inconsistent with the truth values of its components, and thus should be considered incorrect. 
Option e) ' b) and c)' is problematic because it references a 'c)' option that does not exist in the provided list, and it pairs a false statement with a non-existent option, making it invalid as a coherent choice. 
Overall, Option a) stands as the only true statement among the presented choices, while the others contain factual inaccuracies or structural inconsistencies that render them false.
