Simple answer?
C - Groundwater
Water and air fill the spaces down to the zone of saturation, i.e. the water table, though its not really a flat surface in the ground. As one goes deeper, saltwater encroaches becoming brines.
In some areas where the geology is right and structural traps exist in the formations, oil and natural gas can occupy fractures and pore spaces.

In small spaces and cracks, capillary action draws water into spaces that might otherwise not be occupied. This mechanism, combined with frost/freezing action is how rocks are pushed up through the ground over the years, and how after winter, farmers need to be on the lookout for new rocks on the surface.
Freezing (expanding) water is one of the strongest forces on the planet.
