Answer:
Natural selection.
Explanation:
Natural Selection:
Natural selection is the evolution's one of the basic mechanism in which phenotypic variant individuals or organisms survive or reproduce with change in the heritable traits in a population over generations. With the passage of time, this process help the organisms to adapt their environment.
So, the population A and population B organisms interbreed and produce offspring with the process of natural selection.
It is true that the collecting tubules merge to form the ducts of Bellini.
Papillary ducts or collecting ducts or the renal collecting tubules were formerly known as the ducts of Bellini. They are structures which are present in the distal portion of the collecting ducts in our kidneys.
These ducts are formed when collecting tubules merge. They receive the renal filtrate, which is the precursor to urine, from a number of medullary collecting ducts and it empties into a minor calyx. These ducts regulate the reabsorption of water and also balances the electrolytes.
Hence option a is the correct option.
