Final answer:
English is the prime example of a language illustrating cultural transformation due to migrations in a region, particularly in South Asia where it is widely used and has been incorporated into local dialects.
Step-by-step explanation:
The language that is the best example of how culture is transformed as different groups migrate to a region is D. English. This is due to several factors. English has become the lingua franca in many parts of South Asia, including India, both in the north where Hindi is more prevalent, and the south where Dravidian languages like Tamil are common. English's role in India is significant due to colonial history and has since integrated into various aspects of society such as government, military, and education. Because India has a history of diverse migrations and cultural influences, English's prevalence in the region is a testament to these transformations. It is often mixed with local languages, resulting in hybrid forms like Hinglish or Urglish. The Maya culture (answer B) developed the first writing system in the Western Hemisphere, and the Inca developed a road system that rivaled that of the Romans. Also, during the last ice age, lower sea levels made human migration to areas such as North America possible.
