Sometime within the last 10,000 years, a population of the white trout lily gave rise to a new species. The geographic range of the new species is entirely within the geographic range of the original species. Which of the following is described by this example?a. extensive gene flow.
b. anagenesis.
c. sympatric speciation.
d. allopatric specation.

Option C

Explanation:

In case of sympatric speciation, the new species arises from an existing species and these two generation species continue to stay in the same geographical habitat as is the case in this question.  

An example of sympatric speciation is hawthorn fly which exhibit sympatric speciation on the basis of suitable egg laying area. The two generations of hawthorn stay in the same area but they do not mate or interact with each other.

Hence, option C is correct
