The Correct Option is B

Solution and Explanation

The patchy white spots that we see on gray whales are barnacles. The barnacles are just along for the ride. They don?t harm the whales or feed on the whales, like true parasites. In fact, barnacles don?t serve any apparent advantage to the whales. Barnacle and whale together form commensalism type of interaction.

Organisms and Populations

Organisms:

An attached living system that lives in an environment is commonly known as an organism. These organisms are able to retain certain behaviors and structures. Some examples of organisms are plants, animals, bacteria, fungi, and humans. A group of these organisms leads to the formation of a population. The collection of the population forms a community that assists in the operation of ecosystems. 

Each and every organism has the ability to adapt itself to various conditions of the environment. This capacity of organisms is due to their genetic variations. It is due to this only that their probability of survival get increases. For instance, camels adapt themselves to survive in desert areas and polar bears adapt to the extreme cold conditions or situations through their dense fur coat.

Populations:

A collection of organisms or individuals of a species that live, at a specific time, in a geographical area that is well-defined and capable of interbreeding is described as a population.
