What change occurred when carnelian was heated?
Answer and explanation
Correct answer: Its red colour became deeper
The governing concept is the treatment of raw materials in Harappan bead production. Carnelian was a semi-precious stone used for beads, and controlled heating enhanced or deepened its natural red colour. Therefore option D is correct. Heating did not transform the stone into iron or make it dissolve in water, and the key remembered effect in this craft process was colour improvement rather than simply greater hardness.
