Weeds which produce large hollow seeds would most likely be dispersed by

Weeds that produce large hollow seeds are most likely to be dispersed by the wind. This is because the seeds are light in weight and have a cavity, which makes them easy to be carried away by even the slightest breeze. As the wind blows, the seeds are lifted into the air and carried over long distances, where they can fall onto new soil and grow into new plants. The other options - water, insect, and explosion - are less likely for weeds with large hollow seeds as their seeds are not adapted for those forms of dispersal.
