Best answer
Right option is (d) 1800 ⁰C

The best I can explain: The electric arc furnaces can be defined as the furnaces in which charged materials are heated by the application of an electric arc. In general, these furnaces exist in all the sizes, from the smallest to the largest one having capacity of nearly about 400 tons. The electric arc furnaces can achieve temperatures up to 1800 ⁰C.
