Indian city classification: “Jaipur : Bengaluru : Mumbai” — select the description that correctly groups the trio.

Introduction / Context:
Indian civics/geography analogies commonly group cities by political status. Jaipur (Rajasthan), Bengaluru (Karnataka), and Mumbai (Maharashtra) serve as state capitals.

Given Data / Assumptions:

• Jaipur → State capital of Rajasthan.
• Bengaluru → State capital of Karnataka.
• Mumbai → State capital of Maharashtra.

Concept / Approach:
While they are also major business hubs, the most precise political grouping is that all three are state capitals.

Step-by-Step Solution:
1) Confirm each city’s capital status.2) Prefer exact political category over vague economic labels.3) Select “capitals of Indian states.”

Why Other Options Are Wrong:

• Cities in Rajasthan/three biggest villages: Factually incorrect.
• Famous business cities: True for Mumbai/Bengaluru, but Jaipur is less central to that grouping; the political category is cleaner.
• Coastal cities: Jaipur/Bengaluru are inland.

Common Pitfalls:
Choosing a looser economic association when a precise political one exists.

Final Answer:
They are the capitals of Indian states
