How wrought iron can be heat treated?? It has less carbon??

[@shraddhasaxena7085]

In question 10, it is the pig iron in which the percentage of carbon is 2.5-5% and not white cast iron

[@cpatelacademy]

pig iron has got 4-5 wt% C and white cast iron or simply cast iron has greater than 2.1 wt%C and there is exact upper limit of cast iron but it can go upto 6.67 wt%. Practically it is upto 2-3.5 wt% in cast iron. That is why this option has been chosen.
