When a nova occurs, we see a star suddenly brighten dramatically and then fade again. What causes this to happen?

(a)   The outermost layer of a white dwarf is blasted into space by nuclear reactions, without harming the white dwarf itself.
(b)   A white dwarf is destroyed by a cataclysmic explosion, after mass is transferred to it from a companion in a binary star system.
(c)   Mass is blasted into space from the surface of a neutron star, after being transferred there from a companion in a binary star system.
