Which of the following cities is known as the 'Silicon Valley of India' due to…

Indian cities are often given industry-based nicknames that echo global hubs when they develop a dominant, identifiable industry cluster: the label 'Silicon Valley of India' specifically marks a city with a large, long-established concentration of IT/software companies, R&D centres, and a thriving tech start-up ecosystem, paralleling how California's Silicon Valley is defined by its density of technology firms.

Bengaluru has carried this title since the IT boom of the 1980s-90s, when major Indian and multinational software and hardware companies set up large operations there. Over the following decades it added global R&D campuses and one of India's largest start-up ecosystems, giving it a scale and depth of IT-industry concentration that no other Indian city matches, which is why it is widely known as the 'Silicon Valley of India'.

• Pune: known chiefly for automobile and precision-engineering manufacturing and its educational institutions, not for a comparable IT-industry concentration.

• Gurugram: grown mainly around corporate offices, real estate, and financial/business services in the Delhi-NCR region, a corporate-and-finance-led profile rather than a decades-old software hub.

• Hyderabad: has its own genuine and growing IT sector, but this is tied to its own distinct nickname built around its dedicated technology district, rather than the title asked about here.
