I believe the answer is Yy. Although Y represents the dominant trait for yellow, it being paired with the recessive trait, y, has the chance of a plant with green seeds to be produced in the next generation.
        
                    
             
        
        
        
The scientific definition of evolution refers to changes in a species or population over time. 
Evolution is a long-term process. It may take millions of years and several generation for an evolution to occur. The cause of evolution can be genetic as well as environmental. The evolution is a result of mutation. Evolution generally gives rise to new species, that is different from its ancestral population. 
Population is a group of similar type of organisms.  These organisms live in the same habitat, require same resources and have same kind of habits. The most essential criteria that defines a population is that the organisms of a population can mate with each other and produce offspring.

Answer:
 B) speciation.
Explanation:
The Galapagos island is known for the different varieties of finches (species of birds) which could be distinguished on the basis of different beak shapes and size.
This is the result of the selection pressure which led to the divergence of the species on the island through a mechanism called adaptive radiation.
Since the adaptive radiation leads to the formation of different species on the same island, the process of formation species is known as the speciation.
Thus, speciation is the correct answer.
