The correct answer is (a) Brass lamp making.
Nachiarkoil is a town in Tamil Nadu, India. It is famous for its traditional craft of brass lamp making. The town has a long history of this craft, and it is still practiced by many families today. The lamps are made from brass, which is a type of alloy that is made from copper and zinc. The lamps are made by hand, and they are decorated with intricate designs. They are used in temples and homes, and they are also popular souvenirs.
Brass lamp making is a very skilled craft, and it requires a lot of patience and attention to detail. The first step in making a brass lamp is to melt the brass and pour it into a mold. Once the brass has cooled, it is removed from the mold and shaped into the desired form. The lamp is then decorated with intricate designs, which are often made using a hammer and chisel. The final step is to polish the lamp, which gives it a shiny finish.
Brass lamp making is a very important part of the culture of Nachiarkoil. It is a craft that has been passed down from generation to generation, and it is a source of pride for the people of the town. The lamps are not only beautiful, but they are also functional. They provide light in homes and temples, and they are also used in religious ceremonies.
