3% Hydrogen Peroxide has an oral LD50 of 900 mg/kg. Acetic Acid has an oral LD50 of 3310 mg/kg. Which one is more hazardous to consume?

A. They are both non-toxic
B. Acetic Acid
C. Hydrogen Peroxide
D. They are both toxic

I thought that the higher the number the more lethal or hazardous it is to consume. Hydrogen peroxide 900 / 2 = 450 and Acetic acid 3310 / 2 = 1,655 and selected B. Acetic acid because it was higher and the answer was wrong? Please explain. Thank you!
