Solution

The correct option is B Manganese
In the manufacture of steel, manganese is used to make steel strong.
Manganese removes oxygen and sulfur when iron ore (an iron and oxygen compound) is converted into iron. It also is an essential alloy that helps convert iron into steel. As an alloy it decreases the brittleness of steel and imparts strength.
