• B. Q
• C. R
• D. either Q or P

Answer 1

The correct option is B Q

Some metals like iron, cobalt, nickel, etc. are magnetic materials. i.e, they easily get attracted to the magnet and it can also be magnetized.

Also, copper is a weak magnetic material. It interacts with magnets in the presence of a strong magnetic field.

So, rings made up of copper and nickel can be placed in the group of magnetic materials.

Hence, the answer is B.
