Option C, Each subpopulation is linked to all other subpopulations by dispersal.

Explanation:

Each sub-population with in a metapopulation is not only connected by the dispersal distance travelled by an organism but also by the distance between the patches on which two sub population live. There are several other factors that limitise the concept of connection of subpopulation by dispersal factor and these vulnerable factors are - properties of terrain between the patches and its adverse affect on the dispersal behaviour of dispersing agent/species.

Hence, option C is correct.
