“Dhokra” refers to an ancient technique of:

Metal casting
Wood carving
Stone sculpture
Weaving

The correct answer is: Metal casting.

Dhokra is an ancient lost-wax casting technique used to make decorative metal objects, such as sculptures, jewelry, and utensils. The technique is thought to have originated in India over 2,000 years ago, and it is still practiced today in many parts of the country.

To create a dhokra object, the artist first creates a model of the desired object out of wax. The model is then coated with a layer of clay, and the clay is allowed to dry. Once the clay is dry, the artist heats it until the wax melts and drips out, leaving a hollow mold. The mold is then filled with molten metal, and the metal is allowed to cool and harden. Once the metal has cooled, the mold is broken open, and the finished object is removed.

Dhokra objects are typically made of brass or bronze, and they are often decorated with intricate patterns and designs. The technique is known for its high level of craftsmanship, and dhokra objects are prized for their beauty and artistry.
