Answer:
a and e are correct

Data provided in the question:
Daily recommended intake of Vitamin C for Brent = 90 mg/day.

Therefore,
If Brent is consuming 900 and 1000 mg of vitamin C per day, the Brent is
consuming megadose amounts of vitamin.
Hence,
900 mg and 1000 mg represent almost 9-10 times extra intake of
vitamin C. i.e a and e are correct
