Q1:

Assertion (A): Copper is a good conductor of electricity. Reason (R): Copper has a face centred cubic lattice.

A Both A and R are true and R is correct explanation of A

B Both A and R are true but R is not correct explanation of A

C A is true but R is false

D A is false but R is true

ANS:B - Both A and R are true but R is not correct explanation of A

Conductivity does not depend on lattice structure.
