Read the passage and answer the questions:

Chanhudaro is a tiny settlement (less than 7 hectares), almost exclusively devoted to craft production. including bead-making, shell-cutting, metal-working, seal-making and weight-making. The variety of materials used to make beads is remarkable: stones like carnelian, jasper, crystal, quartz and steatite; metals like copper, bronze and gold; and shell, faience, and terracotta or burnt clay. Some beads were made of two or more stones, cemented together, some of stone with gold caps. The shapes were numerous-disc-shaped, cylindrical, spherical, barrel-shaped, segmented.

Which of the following is a red coloured stone used for making beads by the people of Harappan civilization?

Carnelian

The correct answer is Option (2) → Carnelian

Archaeological experiments revealed that carnelian beads acquired their red color by firing the yellowish raw material at various stages of production. Nodules were initially chipped into rough shapes and then finely flaked to obtain the final form. Grinding, polishing, and drilling were the final steps in the bead-making process. Specialized drills have been discovered in Chanhudaro, Lothal, and Dholavira.
