A
True
B
False
C
Either A or B
D
None of the above
Explanation: 

Detailed explanation-1: -Magnets do not attract all metallic objects. They can only attract magnetic materials like iron, cobalt and nickel.

Detailed explanation-2: -Only ferromagnetic materials such as iron, cobalt, and nickel are attracted to magnetic fields strong enough to be truly considered magnetic. However, all metals can be placed into one of three categories: Ferromagnetic.

Detailed explanation-3: -Metals That Don’t Attract Magnets Certain metals in their natural states such as aluminium, copper, brass, lead gold, and silver don’t attract magnets due to the fact they are weak metals. However, properties including iron and steel can be added to these metals in order to make them magnetic.

Detailed explanation-4: -Magnetism. Magnet attract all metals : FALSE, magnetic materials are always made of meta, but not all metals are magnetic such as iron is magnetic while copper is not magnetic.

Detailed explanation-5: -Magnetic materials are always made of metal, but not all metals are magnetic. Iron is magnetic, so any metal with iron in it will be attracted to a magnet. Steel contains iron, so a steel paperclip will be attracted to a magnet too. Most other metals, for example aluminium, copper and gold, are NOT magnetic.
