All these answers are correct. b. included both blowing air through and adding ingredients to molten iron. c. was also developed by an American, William Kelly. d. included blowing air through molten iron. e. involved adding ingredients to molten iron.

Answer 1

Answer:

The correct option is: a. All these answers are correct

Explanation:

The Bessemer process was the first industrial steel-making process by using pig iron in its molten state developed by English inventor, Sir Henry Bessemer in 1856.

In this method, air is blown through the molten iron to remove the impurities present by oxidation, which increases the temperature of the molten iron. After the removal of impurities, certain additives are also added to it.

A similar method was also developed by the American inventor, William Kelly in the year 1851.

Therefore, all the given options are correct.
