Which of the following statements is most relevant to migration?

Migration is a natural process that involves the movement of organisms from one location to another in search of better living conditions or to escape from unfavourable circumstances. These stressful conditions could include a lack of food, water, or shelter, extreme weather conditions, or changes in the environment that make it difficult for organisms to survive. Migration allows organisms to adapt to these challenges and find a new habitat where they can thrive. For instance, animals like Siberian cranes migrate from colder to warmer areas in search of food, shelter, and breeding sites, returning to their native habitat when the environmental conditions return to normal.
