Solution

The correct options are

When a mixture of silicon and coke is heated in an electric furnace, silicon carbide is formed.This is an endothermic reaction since heat from the furnace is used for chemical reaction as well as it is a combination reaction because silicon and carbon are combining to form silicon carbide.
