Which of these is the correct SI unit for capacitance?

Farad-Joules
By using a dielectric, it is possible to store more energy in a capacitor. Why is this?
The dielectric replaces air, which breaks down when the electric fields get strong enough
The dielectric can store excess energy
The dielectric changes the distance between the two plates of the capacitor
The dielectric provides a direct energy source to the capacitor
