Best answer
Right option is (a) True

The best explanation: In electric furnaces, the process of de-slagging is mainly carried out to remove the slag impurities from the furnace. During the refining process, some of the undesirable metals are oxidized and enters into the slag phase. So the furnace is tilted to pour out the slag from the furnace through the slag door.
