1. outer electrons of elements in good conductors are loosely held and are able to migrate readily.

2. outer electrons of elements in good conductors are held tightly and are able to migrate readily.

3. there are no outer electrons of elements in good conductors.

Explanation:

An electric conductor is a material that offers little resistance to the movement of the electric charge. Its atoms are characterized by having few electrons in their valence layer, so it doesn't take much energy for them to jump from one atom to another.

Metals consist of compact packages of metal atoms with tiny free electrons floating in the spaces between the atoms, free to travel along the entire metal. The presence of these free electrons makes all metals good conductors.
