Answer:

The correct option is: A) sympatric speciation

Explanation:

Sympatric speciation is a type of geographic mode of speciation. It refers to the evolution of two or more than two new or descendant species from the  existing common descent. The new species and the ancestral species all live in the same geographic area or location.

The common example of this speciation is insects like moths that become dependent on different plants belonging to the same geographical area.
