S
there are four types of orbitals:
s: shaped like a
an e level can contain only s orbital, making up the "s sublevel".
p :
shaped like
an elevel can contain_ p orbitals, making up the “p sublevel".
d: shaped like double dumbbells
an e level can containe d orbitals, making up the "d sublevel".
too complex to draw or describe
an e level can contain_ forbitals, making up the "f sublevel".

where's the diagram?

metals are good conductor of electricity. it has free electrons on their surface. according to electron pool theory, each atom present in a metal crystal losses all of its valence electron and as a result a pool of free is form. these pool of electrons are free to move and   conduct electricity easily   while making metal as good conductor.

the correct answer is a. the ability of electrons to flow throughout the metal.
