In the city of New Constantine, Japas and Haruhana....

Which of the following most logically completes the argument below?

In the city of New Constantine, Japas and Haruhana are restaurant chains that compete for business. In an effort to lure travelers and residents to come out for dining, the owners of Japas released promotional materials saying that more customers go eat at Japas than at competitor Haruhana. A pamphlet from the largest Haruhana restaurant in New Constantine claims that more people eat at that restaurant than at the Japas across the street. If both of these sources are accurate, however, the "Restaurant Guide" for the region must be in error in stating that ___________.

(A) the average meal is larger at the largest Haruhana restaurant in New Constantine than at the Japas across the street.

(B) there is only one Haruhana restaurant in New Constantine that is larger than the Japas across the street.

(C) more people eat at Haruhana than eat at the Japas across the street.

(D) the Japas across the street is the largest Japas restaurant in New Constantine.

(E) the Japas across the street is the only Japas restaurant in New Constantine.

Can someone explain why is the answer as given in OA?
