Critical Reasoning

Some good cooks are gourmet cooks who pride themselves on always using extravagantly rich ingredients in elaborate recipes. Some good cooks can be characterized as fast-food cooks. They may use rich ingredients as long as the recipes are easy to follow and take little time. Other good cooks are health food enthusiasts, who are concerned primarily with the nutritional value of food. But even though not all good cooks are big eaters, they all enjoy preparing and serving food.

If the information in the passage is true, which one of the following CANNOT be true?

(A) Most good cooks do not use extravagantly rich ingredients.

(B) Everyone who enjoys preparing and serving food is a good cook.

(C) More good cooks who use extravagantly rich ingredients are big eaters than are good cooks who do not use such ingredients.

(D) There are fewer good cooks who enjoy serving and preparing food than there are good cooks who are big eaters.

(E) Gourmet cooks, fast-food cooks, and cooks who are health food enthusiasts are all big eaters.
OA after discussions

would go for D

D seems to be the only one that cannot be true. others- may be may not be. we do not have enough information.

say there are 10 good cooks in all
1)All good cooks enjoy preparing/serving: 10
2)not all good cooks are big eaters: 0-9

1) can never be lesser than 2)

IMO D

I would go with D as D destroys the last sentence of the argument

It seems to me that the right answer is D
