Explanation: In English grammar, the comparative degree is used to compare two entities, indicating that one has more of a quality than the other. The superlative degree, on the other hand, is used to indicate the highest degree of a quality among more than two entities. The comparative form of "rich" is "richer," and the superlative form is "richest."
The original sentence, "Bengaluru is one of the richest cities in India," uses the superlative form "richest" to indicate that Bengaluru is among the top cities in terms of wealth. However, the task is to change this sentence into the comparative degree, which means we need to compare Bengaluru with other cities in India using the comparative form "richer."
Option A, "Bengaluru is richer than any other cities in India," is incorrect because it implies that Bengaluru is richer than every other city in India, which is not what the original sentence suggests. The original sentence indicates that Bengaluru is among the richest, not necessarily the richest.
Option B, "Bengaluru is richer than most other cities in India," is correct because it accurately uses the comparative form "richer" and specifies that Bengaluru is richer than most other cities in India, which aligns with the original sentence's meaning that Bengaluru is one of the richest cities.
Option C, "No other cities in India are as rich as Bengaluru," is incorrect because it uses the superlative form "as rich as" and implies that no other city is as rich as Bengaluru, which is not what the original sentence suggests. The original sentence indicates that Bengaluru is among the richest, not necessarily the richest.
Option D, "None of the above," is incorrect because one of the provided options (Option B) is correct and accurately reflects the comparative form needed to compare Bengaluru with other cities in India.
In summary, the correct answer is Option B, "Bengaluru is richer than most other cities in India," because it correctly uses the comparative form and maintains the original meaning of the sentence.
