Select the correct answer using the code given below:
Answer: D
Notes:
Explanation:
- Statement 1 is incorrect: The American Cordillera is an almost unbroken chain of mountain ranges that forms the western backbone of North America, South America, and continues through the Scotia Arc into Antarctica (Antarctic Peninsula).
