Q. Metals known to Indus Valley Civilisation were

(a) Gold, copper, silver but not iron

(b) Silver, iron, bronze but not gold

(c) Iron, copper, gold but not silver

(d) Zinc, silver, iron but not gold

Ans: (a) Gold, copper, silver but not iron

Explanation: The metals known to the Indus Valley Civilization were (a) gold, copper, and silver, but not iron.

Archaeological excavations at various Indus Valley sites have revealed evidence of the use of these metals. Gold was used for making jewelry and ornaments, as well as for decorative purposes. Copper was widely used for making tools, utensils, and various artifacts. Silver was also used for making ornaments and decorative items.

Iron, however, was not widely known or used during the Indus Valley Civilization. Iron smelting technology was not yet developed, and iron tools and artifacts were not commonly found in archaeological remains from that period.

Therefore, the correct answer is (a) gold, copper, silver but not iron.
