Critical Reasoning

Which of the following most logically completes the argument below?
According to promotional material published by the city of Springfield, more tourists
stay in hotels in Springfield than stay in the neighboring city of Harristown. A brochure
from the largest hotel in Harristown claims that more tourists stay in that hotel than
stay in the Royal Arms Hotel in Springfield. If both of these sources are accurate,
however, the "•Report on Tourism"– for the region must be in error in stating that
______.
A. the average length of stay is longer at the largest hotel in Harristown than it is
at the Royal Arms Hotel
B. there is only one hotel in Harristown that is larger than the Royal Arms Hotel
C. more tourists stay in hotels in Harristown than stay in the Royal Arms Hotel
D. the Royal Arms Hotel is the largest hotel in Springfield
E. the Royal Arms Hotel is the only hotel in Springfield

Any thoughts??....I am just clueless here....I chose C....

Ans should be E.
Springfield has more tourists than has Morristown. But Largest Hotel of M has more tourists than has the Royal Arms of S.
So there must be more hotels in S so that the total number of Tourists in S is more than M.

will some expert please provide some comments how to break it down?
