The statement that one of the least likely drivers for this speciation event is the similarity in the method of pollination. Thus, the correct option for this question is C.
What is meant by Speciation?
Speciation may be defined as the process of the formation of new species from the parental one. It occurs when members of similar populations no longer interbreed in order to produce fertile offspring within their natural environment.
The mechanism of speciation always occurs when members of the same population share some different characteristics over a large period of time. So, the similarity in the method of pollination would not be a relevant event for the process of speciation to occur.
Therefore, the similarity in the method of pollination is the statement that one of the least likely drivers for this speciation event. Thus, the correct option for this question is C.
