Newspaper publishers earn their profits primarily from advertising rev

Newspaper publishers earn their profits primarily from advertising revenue, and potential advertisers are more likely to advertise in newspapers with a wide circulation a large number of subscribers and other readers than with other newspapers. But the circulation of the newspaper that is currently the most profitable one in this city has steadily declined during the last two years, while the circulation of one of its competitors has steadily increased.

Any of the following, if true, would help explain the apparent discrepancy between the two statements above EXCEPT:

A. Advertisers generally switch from the most widely circulated newspaper to another one only when the other one becomes the most widely circulated newspaper instead.
B. Advertising rates charged by the most profitable newspaper in the city are significantly higher than those charged by its competitors.
C. The most profitable newspaper in the city receives revenue from its subscribers as well from advertisers.
D. The circulation of the most profitable newspaper in the city is still greater than than of any of its competitors.
E. The number of newspapers competing viably with the most profitable newspaper in the city has increased during the last two years.

Can someone please explain the OA ?
Acc to me (Yes i got it right) if the # of newspaper competitors have increased then its circulation share will go down, but it can still remain the most profitable one in the city
Lets say :
Before competition :
A -----> 1000 subs (A gets all the ads and hence makes the max profits)
B -----> 100 subs
TOTAL subs 1100
After some time
A -----> 500 (Subs went down steadily)
B -----> 200 (Subs went up steadily)
C -----> 100
D -----> 100
E -----> 150
F -----> 50

But A is still making the most profit (E helps explaining this)

Please correct me if I am wrong. Thanks in advance.
