The correct answer is Amlanand Ghosh.

Key Points

• Prof Amlanand Ghosh excavated the Kalibangan site in 1952.
• The Kalibangan civilization is supposed to older than 4000 BC.
• This Rajasthan civilization was the first metropolis state in India.
• Kalibangan lies along with the left Bank of the dried-up bed of river Ghaggar.
• The site contains both pre-Harappan and Harappan remains, and therein can be seen the transition between the two cultures.
• Although the pre-Harappan culture worked copper and produced pottery, it had no writing system, and its ruins lack the orderly layout and use of baked brick that is found in the later Harappan sites.
• The Harappan remains include a cemetery and a fortified citadel.

The correct answer is Silver.

Key Points

• Gold
  • It is one of the softest metals, and this quality makes it easier to design it in various jewelry designs.
  • It is tough making 24 karat gold jewelry. Other metals have to be added to it to increase its durability and strength.
  • If you wish to know what is 24 karat gold, you must understand that 24 karat gold is the purest form of this yellow metal.
  • Although 24 karat is pure gold, a jewelry piece made up of this purity is not solid and flexible enough.
  • When creating and crafting beautiful, intricately designed, and patterned gold jewelry, the metal needs to be added with other alloys to lend it the necessary strength.
  • The metals usually added to gold metal are zinc, nickel, silver, copper, etc. Hence, Option 3 is correct.
  • This is because when gold melts its state will change into a liquid.
  • Gold will like water so it flows and it will become difficult to mold.
  • So copper is added to gold which is there in the liquid state, so it will harden gold a little bit to prevent it from flowing which will be easy to mold gold to make ornaments.
