A
monopoly
B
vertical integration method
C
Bessemer Process
D
Carnegie Process
Explanation: 

Detailed explanation-1: -The Bessemer process was the first inexpensive industrial process for the mass production of steel from molten pig iron before the development of the open hearth furnace. The key principle is removal of impurities from the iron by oxidation with air being blown through the molten iron.

Detailed explanation-2: -The bessemer process reduces molten pig iron in so-called bessemer converters-egg-shaped, silica, clay, or dolomite-lined containers with capacities of 5 to 30 tons of molten iron. An opening at the narrow upper portion of the bessemer converter allows iron to be introduced and the finished product to be poured out.

Detailed explanation-3: -noun. Bes·se·mer process ˈbe-sə-mər-: a process of making steel from pig iron by burning out carbon and other impurities by means of a blast of air forced through the molten metal.

Detailed explanation-4: -Though named after Sir Henry Bessemer of England, the process evolved from the contributions of many investigators before it could be used on a broad commercial basis. It was apparently conceived independently and almost concurrently by Bessemer and by William Kelly of the United States.

Detailed explanation-5: -The Bessemer Steel Process was a method of producing high-quality steel by shooting air into molten steel to burn off carbon and other impurities. It was named after the British inventor Sir Henry Bessemer, who worked to develop the process in the 1850s.
