Verified by Toppr

Explosive mechanism is a method of self dispersal of seeds by the plants. Some plants distribute their seeds by violently ejecting them so that they fall well away from the parent plant. This is explosive dispersal. An example of this is plants which belong to the pea family (Leguminoceae). They produce seed pods which dry in the sun.
Thus, the correct answer is option B.
