A. Only if her intake is consistently less than 70% of the RDA would she be at great risk of nutritional deficiency.

Explanation:

In an adult women blood contain 70% of the entire body iron.However menstruation  takes certain proportion of  iron in menstrual flow .Besides, 1 mg of iron is lost daily inform the mucous membranes and regular skin sheds. Therefore  daily  dietary and supplement intake of iron  should be consumed  so that  the set point of 70% is  maintained. Provided Tina can maintain  her  blood plasma iron concentration at  70%,  with her 15 mg intake but not less than this value she would not not experience any nutritional deficiencies.  

Thus, it is when her blood plasma levels(body %) falls below the blood  iron percentage of 70, that she will be at risk.
