Explanations:The question asks for the union territory with the highest population as per the 2011 census. Union territories in India are governed directly by the Union Government and are distinct from states. The 2011 census provides the most recent official population data for these territories.
Among the union territories, Delhi stands out as the most populous. This is due to its status as a major urban center and the national capital. Delhi is home to a large number of government offices, businesses, and educational institutions, which attract a significant population. The 2011 census recorded Delhi's population at approximately 16.78 million, making it the most populous union territory in India.
Other union territories like Puducherry, Daman and Diu, and Dadra and Nagar Haveli have much smaller populations. Puducherry, for example, has a population of around 1.24 million, while Daman and Diu and Dadra and Nagar Haveli have populations of around 243,000 and 343,000, respectively. These numbers are significantly lower than Delhi's population, making them incorrect choices for the question.
Understanding the population distribution among union territories is important for various competitive examinations, as it tests the candidate's knowledge of demographic data and urban centers in India. It is crucial to recognize that while Delhi is a union territory, its population is comparable to that of many states, reflecting its significant role as the national capital and a major urban hub.
