Which of the following sentence should be the FIRST after rearrangement ?

The sentence can be arranged in the following way for forming a paragraph. (The index number has been retained for ease of understanding.)
(B)Many have been crying foul over the entry of organized retail stores expressing concern over their impact on small store owners. (This is the opening sentence as it lays the premise for subsquent formation of paragraph.)
(E)But a study conducted over a period of two years goes a long way towards allaying these fears. (This sentence will be second as it contradicts the premise laid down in the first sentence.)
(A)According to it organized retail stores are not wolves at the doors of friendly neighbourhood grocery stores as there is room for expansion of both.
(This sentence will naturally form the next sentence as it refers to the study mentioned in the previous sentence.)
(DIn spite of this potential for expansion it is doubtless that the small store owners face a decline in profit in initial years if organized retailers set up stores in the vicinity. (This will form the next sentence as it contradicts the idea of expasion mentioned in the previous sentence.
(F)This impact however wears off once they learn to take on the competition which in turn enhances efficiency all around. (This appends the premise of small store owners fearing the competition.)
(C)The final winner in the competition however is the common man who gets to choose between the most suitable options and in turn fights with the essential commodities. (This naturally is concluding statement as it lays conclusion to the ongoing discussion.)
Hence, B forms the first sentence.
