Fish currently costs

the future, profit margins will be higher at seafood stores within the city than at
suburban seafood stores.
For the purposes of evaluating the argument, it would be most useful to know
whether.
(A)more fish wholesalers are located within the city than in the surrounding suburbs.
(B) Any people who currently own seafood stores in the suburbs surrounding Eastville
will relocate their businesses nearer to the city
(C) The wholesale price of fish is likely to fall in the future
(D)Fish has always cost about the same at seafood stores throughout Eastville and its
surrounding suburbs.
(E) Seafood stores within the city will in the future set prices that are lower than those
at suburban seafood stores.

Can some experts explain the Best Option?

OA E

We know that city seafood stores and suburban seafood stores buy their food from the same wholesalers and have similar expenses. We know that the fish costs the same in both locations. So, to start, the stores should have similar profit margins. We're told that the city seafood stores are going to get a tax break, which, in effect will lower their costs.. So if the costs of city stores are less than the cost of suburban stores, it stands to reason that their profit margins will now be larger. However, if there was a reason to believe that their prices were going to decrease, we could no longer make this assumption, as the lower costs conferred by a lower tax rate would be offset by a lower unit revenue from a decrease in price. This is what E gives us. The lower taxes might reduce the cost, but a lower price would reduce their unit revenue, leaving us, at best, uncertain about profit margins.
