The RDA (Recommended Dietary Allowance) is established based on the EAR (Estimated Average Requirement), which is the amount of a nutrient that is estimated to meet the needs of about 50% of the population. The RDA is then set higher than the EAR to ensure that the needs of nearly all (97-98%) of the population are met. Therefore, choice B is the correct answer. The DRI (Dietary Reference Intake) is a set of nutrient recommendations that includes the EAR, RDA, UL (Tolerable Upper Intake Level), and AI (Adequate Intake). The UL is the highest amount of a nutrient that is safe to consume daily without causing harm, while the AI is used when there is not enough evidence to establish an EAR or RDA for a certain nutrient.
