The correct options are
A Metal paper clip
C Pencil lead
D Iron bangle
Metals are conducting in nature. They allow electricity to pass through them. So, a metal paper clip, an iron bangle and pencil lead are conductors. Whereas an eraser is not conductor because it don't allow electricity to flow through them. It is insulator.
