Weird CR. Not able to understand.

In January of last year, Fastfood King started using a new lowfat oil to cook its Fast Fries, instead of the less
healthful corn oil that it had been using. Now Fastfood King is planning to switch back, saying that the change has
hurt sales of Fast Fries. However, this claim is incorrect, since according to Fastfood King’s own sales figures,
Fastfood King sold 10 percent more Fast Fries last year than in the previous year. Which of the following, if true,
most strongly supports the argument against Fastfood King’s claim?
- Total sales of all foods at Fastfood King’s locations increased by less than 10 percent last year.
- Fastfood King enjoys higher profit margins on its Soft Drinks than it does on Fast Fries.
- Fastfood King’s customers prefer the taste of Fast Fries cooked in corn oil to Fast Fries cooked in lowfat oil.
- The number of customers that visited Fastfood King locations was more than 20 percent higher last year than the
year before.
- The year before last, Fastfood King experienced a 20 percent increase in Fast Fries sales over the previous year.

I am not able to analyze this argument.
It is conflicting in itself.
On one hand it says, Now Fastfood King is planning to switch back, saying that the change has
hurt sales of Fast Fries. and on the other hand it is just denying this fact and says that
However, this claim is incorrect, since according to Fastfood King’s own sales figures,
Fastfood King sold 10 percent more Fast Fries last year than in the previous year

Forget about strenthening the argument, firstly tell me how can both these things be true at the same time ?
