Question

A zoologist is trying to find out whether rabbits need vitamin C in their diet. Assuming that a sufficiently large number of rabbits is used and adequate controls are applied, the best design of experiment would be to give the rabbits:
a.) an artificial diet of pure protein, carbohydrate, fats, minerals and vitamins but lacking vitamin C
b.) an artificial diet as above but with extra vitamin C
c.) a natural diet of grass, carrots, etc. but with added vitamin C
d.) natural food but of one kind only, e.g. exclusively grass or exclusively carrots?
Justify your choice and say why you excluded the other alternatives.
