Answer:
Upper Limit (UL)
Explanation:
Dietary Reference Intake (DRI) is a group of four nutrient based values i.e. Adequate Intake (AI), Recommended Dietary Allowance (RDA), Estimated Average Requirement (EAR) and Tolerable Upper Intake Level (UL). RDA is the average daily dietary intake sufficient to meet level of nutrients required by an individual. RDA depends on EAR. If EAR cant be estimated for some reasons, RDA cant be calculated and instead AI is used to estimate sufficient dietary intake. AI is derived on experimental basis by observing average nutrient intake by group of healthy individuals.
UL is the highest level of nutrient intake possible on a daily basis without causing harm to the individual. Intake above UL increases the risk of adverse effects. UL is higher than RDA or AI. Hence, Marni could be informed by UL the maximum amount of vitamin A she could consume without risk of side effects.
I'd say probably C

The brain stem which is composed of the Pons, The Medulla, and the Midbrain serve a very vital function... They control the functions that keep you alive; Heart Rate, Respiratory Rate, Breathing input and output, Blood pressure, as well a vasomotor functions. So taking this into account, an injury to the brain stem is extremely bad, as that can and will most definitely be very lethal.
