Answer

Brief Explanations:

For life to appear, a solid crust first needed to form to provide a stable surface. Volcanic activity then released various gases and water - vapor into the atmosphere. The water - vapor condensed and formed oceans. Atmosphere formation and crust cooling are not in the correct order for life - origin processes as crust formation is a precursor. Meteorite impacts and solar nebula are more related to the early formation of the solar system and Earth but not directly in the sequence for life appearance in the most direct sense compared to crust - volcanic - ocean sequence. Oxygen production is important for more complex life forms but comes later in the process after basic life - supporting environments are established.

Answer:

Crust formation → volcanic activity → ocean formation
