D Mario must have changed the data

Answer 1

Choice B is correct here. Especially when experimenting with illnesses like the flu, three test subjects is not sufficient enough. Cures can change based on age, size, gender, etc. In addition, everyone's body reacts different to illness cures, meaning he needs to test more subjects before fully concluding that Vitamin C is a cure.
