Answer:
Cyanobacteria. (Ans. A)
Explanation:
Cyanobacteria are prokaryotes, are a phylum of bacteria. They are also called as blue-green algae and obtain their energy through the process of photosynthesis. They are commonly found in fresh water and terrestrial environment such as land, in rocks even in animal cells (fur).
Cyanobacteria are photosynthetic (oxygenic) bacteria. They harvest the energy of sun, absorb carbon dioxide and release O2. Cyanobacteria also contain chlorophyll such as plants and algae and convert carbon dioxide to sugar through the process of carbon fixation.
Cyanobacteria lack nucleus and other organelles like found in algae and plants. Instead of these they have double outer cell membrane and folded inner thylakoid member which are used in the process of photosynthesis.

the correct answer is A- Reproductive isolation occurred through behavioral isolation
A process of formation of a new species from an existing species is called speciation. New species may formed due to geographical or reproductive barriers which isolates the members of a population of a species to form a new species.
In the given question, speciation in In the leopard frogs occurred due to a particular or specific call given by males to the females. The courtship call lead to reproductive isolation due to change in behavior. Such type of behavioral change will help in recognizing mates of the same species and this will act as a reproductive barrier among the other related species.
