Critical Reasoning

BurgerMan offers an assortment of packaged ready-to-eat sandwich items. This festive season it wants to add to its menu the egg-based mayonnaise sandwiches, which are considered non-vegetarian, and the vegetarian mayonnaise sandwiches, but can stock only one of the two types. Only one-third of BurgerMan's customers are vegetarians. Hence, an increase in revenue being the main motive behind the new addition to the shelves, BurgerMan should add only the egg-based mayonnaise sandwiches to its selection.

Which of the following, if true, most seriously weakens the argument?

A
The proportion of sales from non-vegetarian customers is almost always higher than that from the vegetarian section.

B
The cost of the non-egg mayonnaise is substantially higher due to the ingredients that have to be used instead of egg and that puts the item in the expensive category.

C
Difference in the taste of the two types of mayonnaise sandwiches being negligible, the non-vegetarian customers will go for the vegetarian ones in the absence of its non-vegetarian counterpart, but the vegetarians will never buy the egg-based ones.

D
BurgerMan stocks an assortment of sandwiches and does not anticipate any substantial increase in overall sales revenue from the new entrant.

E
A lot of people nowadays do not consider eggs a non-vegetarian product and have included it liberally in their diet.
