Big businesses .

Big businesses "controlled all phases of production" .

Option: B

The big businesses are immense because they believe in producing all the basic requirements for leading product of the company.

Applying this strategy business individuals not only earn profit and save money, but also spread their market in large scale by controlling all the phases of production. The turnover increases more by production and selling rather than building franchises across large areas only. Combination of both can lead a firm to top level.
