All of these

Women of childbearing age

Explanation:

The water-soluble vitamin B9 is available naturally as folate and available synthetically as folic acid in fortified supplements

Folate or folic acid is highly essential for women during the childbearing ages, before and during pregnancy.

An RDA of 400 micrograms of folate/folic acid per day should be taken from before the pregnancy period and at least till 12 weeks.

Folic acid plays a major role in the synthesis of red blood cells and in the neural development (brain and spinal cord) of the baby. Folate help prevent congenital neural defects like spina bifida and other birth defects.

Dietary folate alone is not enough to support the needs during childbearing period, hence folic acid supplements can be taken as directed by the physician.  

to increase speed you need to decrease frictiona dn drag hense why sprinters wear tight track suits to keep tight against there skin to keep away from wind and decrease the amount of drag you are carrying.a swimmer will wear the tightest swim suit they can possibly fit into (i was a size 28 swim suit at meets i wore a   size 23) why? because the tighter your clothing is the less drag and negative force you have. the heavier the clothe the slower and more wind gets caught. cotton tends to hold onto alot of sweat and water making it slower then say a track suit (no idea what they are made of but they are really comfy around your answer )
