Answer 1

Pig iron contains 4.3% carbon and it melts at 1130 degrees celsius.

What is pig iron and how is it formed?

• Pig iron consists of 92% iron and contains other elements in trace amounts.
• Other trace elements are carbon, manganese, silicon, and phosphorous that are present in it.
• Carbon constitutes a varying amount of about 4-4.5% while silicon has 0.5 to 6% and phosphorous has 0.1 to 2% contribution.

Thus, the correct option is (c): 4.3% carbon
