Q. Which of the following material was mainly used by the Indus people in the manufacture of seals?
Answer: Steatite
Notes: Steatite, a smooth fine-grained composite rock made of minerals like talc and rich in magnesium, was the most predominant material used in carving small Indus seals. Easy availability in areas surrounding Harappan sites made it an ideal choice. The soft nature of steatite also enabled easy carving of intricate designs and writing symbols by artisans.
