Why?
Yes, their are free electrons but the atoms in solids ar tightly packed too.
Am I right?

Metals are the good conductor, because it have free electrons in the outer most orbital.

Free electrons are the main reason for current conduction. The atoms present in the metal gets ionized with the release of free electrons. But in the case of an insulator, all electrons are tightly bound to the nucleus of the atom. Hence there are no free electrons to carry current.

Because in metal the electrons are closely packed so that the flow of current is easy.

If atoms are tightly packed and no free electrons can it act as conductor @Abdul, no because basic thing need is charge carriers to carry charge, either free electrons or ions in electrolytes.

Can anyone tell me that why B option is wrong? as, lightly packed atoms offer less resistance and conversely good conductor. Hence both A and B are correct.

Electrons when move from there place they create a hole on there place and then next electron come to in this hole to fill up it and create a new hole on there place this process is continue and so electron move thus current start flow.

Free electrons ably interfere with external fields due to their high mobility hence good conduction.

The presence of free electrons in metal make them be good conductor of electricity because current electricity itself is the rate of flow of electrons.

Metals are the good conductor of electricity because they contain free electrons. These free electrons can move easily in the the lattice of metal & carry current along with them. SILVER is the best conductor of electricity.
