The correct answer is A) Hand-painting on fabric.
Kalamkari is a traditional Indian art form that involves hand-painting designs on fabric using a stylus called a kalam. The designs are usually inspired by nature and mythology, and they are often brightly colored. Kalamkari is a labor-intensive process, and it can take several weeks to complete a single piece. However, the finished product is a beautiful and unique work of art.
Option B, embroidery, is a technique that involves using a needle and thread to create designs on fabric. Option C, block printing, is a technique that involves using a carved wooden block to print designs on fabric. Option D, weaving with colored thread, is a technique that involves using colored threads to weave patterns on fabric.
All of these techniques are used to create beautiful works of art, but they are all different from kalamkari. Kalamkari is a unique art form that is characterized by its use of hand-painting and its intricate designs.
