In the given question, a statement of Assertion is followed by a statement of Reason. Mark the correct answer.

Assertion: Harappans were able to make a variety of shapes of beads.
Reason: The knowledge of how to use metals such as iron and copper enabled them to make such beads.

The Assertion is correct but the Reason is incorrect.

Techniques for making beads differed according to the material. Steatite, a very soft stone, was easily worked. Some beads were moulded out of a paste made with steatite powder. This permitted making a variety of shapes, unlike the geometrical forms made out of harder stones.
