Explanations:The question asks about the number of states among Karnataka, Maharashtra, and West Bengal that have at least one city with a population exceeding 1 crore (10 million). Understanding the population sizes of major cities within these states is crucial for answering this question correctly.
Let's examine each state individually:
Karnataka: The state of Karnataka has a significant urban population, with its capital city, Bengaluru, being one of the largest cities in India. According to recent census data, Bengaluru's population exceeds 1 crore. This makes Karnataka one of the states that meet the criteria of having at least one city with a population exceeding 1 crore.
Maharashtra: Maharashtra is home to Mumbai, which is not only the largest city in India but also one of the most populous cities in the world. Mumbai's population is well over 1 crore, making Maharashtra another state that meets the criteria.
West Bengal: West Bengal includes Kolkata, which is one of the oldest and most historic cities in India. Kolkata's population also exceeds 1 crore, thus qualifying West Bengal as a state with at least one city meeting the population criteria.
Given that all three states—Karnataka, Maharashtra, and West Bengal—have at least one city with a population exceeding 1 crore, the correct answer is "D) All of the above."
It is important to note that while other cities within these states may not meet the 1 crore population threshold, the presence of at least one city in each state that does meet the criteria is sufficient to satisfy the question's requirements. This question tests the student's knowledge of urban demography and the ability to identify major cities within specific states based on their population sizes.
