Answer:
The correct answer is - polyploidy.
Explanation:
Speciation can be two types allopatric and sympatric speciation. Sympatric speciation is the process of speciation is developing the new species that diverged from the common ancestral species while the ancestral and developed species both can share the same place or geological area. The main cause of such speciation is due to the change in their genetic level more than environmental conditions.
In this case, the frog's species show differences in their ploidy level as well as their mating call but polyploidy is the most likely the difference that evolved first rather than females call for mating.
Thus, the correct answer is - polyploidy.

Pancreas
It is a large gland behind in the stomach that secretes digestive enzymes in the duodenum. Inside the pancreas are Islet of Langerhans. It is considered as an endocrine gland producing various hormones. Pancreas also produce pancreatic enzymes that act as digestive enzyme that assist in digestion and absorption of nutrients in the small intestine. These helps to break macromolecules such as carbohydrates, proteins and fats.
