Plants that evolved resistance to herbivores were able to diversify rapidly. Some butterflies overcame these defenses and also diversified rapidly. This is an example of .

Escape & radiate Co evolution

Explanation:

Escape and-radiate coevolution, a related type of coevolution, is the point at which a transformative development by either individual in a co evolutionary connection permits versatile radiation or speciation because of the accessibility of environmental chance  Adaptive radiation is the enhancement of a gathering of creatures into structures filling distinctive environmental specialties  The prediction of getaway and-emanate is that another blast of expansion happens through a leap forward in developmental achievement. This success is due to a continuous co evolutionary weapons contest  The result of this procedure is the non concurrent 'radiation' of the speciesHence, the right answer is "escape and radiate coevolution"
