What process heated the early solar nebula as it slowly condensed towards a central protosun?

(a)   Atoms collided with increasing speed as they fell towards the center of the nebula, creating heat.
(b)   Thermonuclear fusion in the protosun was followed by radiative heating of the material in the nebula.
(c)   Heat was released by the formation of molecules such as CO2 and NH3 from atoms, and the condensation of ices from gases such as H2O.
