The following statements about dispersal are correct:

III seeds are important dispersal stages in the life cycles
of most flowering plants.
Option II is false because Colonization of devastated
areas after floods or volcanic eruptions does not primarily depends upon
climate. It depends on disoersal.
Option IV is false
becasause dispersal also occurs on contemporary time scales, not just on an
evolutionary time scale
