Question
How did the temperature of the solar nebula develop?
The nebula formed from cold gas and dust, and it remained cold until sufficient oxygen had accumulated so that combustion was possible.
The nebula formed from cold gas and dust, and it remained cold until nuclear reactions developed.
The gas and dust remained cold as they collapsed to form a much denser nebula. Here friction developed between the particles, and this gradually raised the temperature.
As the nebula collapsed, gravitational potential energy was converted into kinetic energy, and the temperature rose.

Explanation / Answer
the answer is d=As the nebula collapsed, gravitational potential energy was converted into kinetic energy, and the temperature rose.
According to the solar nebula theory the Sun and all the other planets of our Solar System began as a big giant cloud of molecular gas and large amont of dust. Then, about 4.57 billion years ago, some strange phenomenon happened which caused the cloud to collapse under its own gravity
As the cloud contracted itself, its gravitational potential energy got converted into the kinetic energy of the individual gas particles present in them. Collisions between these particles converted this energy into heat which lead to temperature development.
