Which of the following is NOT a continent?

The correct choice is India because it is not classified as a continent; rather, it is a country located on the subcontinent of India, which is part of the larger region of South Asia. Continents are large landmasses typically defined by geographical and cultural criteria, and they are composed of multiple countries. The other options listed—Oceania, South America, and Europe—are all recognized as distinct continents. Oceania comprises numerous islands and countries in the Pacific, South America is the continent that includes countries like Brazil and Argentina, and Europe consists of many nations, including Germany and France. Understanding the definitions and classifications of continents is crucial, especially in geographical studies.
