Explanation:

- Bengaluru is called the “Silicon Valley of India.” This city is the country’s tech hotspot. It's where you’ll find a massive cluster of IT companies, start-ups, and more software engineers than you can count.

- Hyderabad is big in tech too, but it’s more known as “Cyberabad” because of its growth in IT and business process outsourcing.

- Pune is a growing IT hub and has a lot of engineers, but it’s also famous for its education and manufacturing scene.

- Mumbai is India’s financial capital, with a focus on money, media, and business, not software or tech innovation.

That’s why Bengaluru stands out as India’s own Silicon Valley.
