Which of the following Indian cities is popularly known as the Electronic City of India due to its concentration of information technology industries?

Introduction / Context:
India has several major urban centres that specialise in different sectors such as finance, film, manufacturing and information technology. One of these cities has earned the nickname Electronic City of India because of its large number of technology companies, startups and electronic industries. This question tests awareness of that widely used nickname.

Given Data / Assumptions:

- We are asked which city is known as the Electronic City of India. - The options list four large Indian cities with significant economic activity. - We assume familiarity with basic Indian geography and economic roles of cities.

Concept / Approach:
Bengaluru, earlier known as Bangalore, is India leading centre for information technology and software services. It hosts numerous multinational companies, Indian IT giants and startups. The city has a large industrial area called Electronic City, and as a result Bengaluru is popularly associated with electronics and IT. Although Hyderabad and Gurgaon are also important IT hubs, the specific title Electronic City of India is most clearly linked with Bengaluru.

Step-by-Step Solution:
Step 1: Recall that Bengaluru is often called the Silicon Valley of India because of its huge IT sector. Step 2: Remember that Bengaluru has a major industrial park literally named Electronic City, housing many technology firms. Step 3: Compare this with Hyderabad, which is branded as Cyberabad or the City of Pearls, and with Gurgaon, which is known as a corporate and outsourcing hub but not specifically as Electronic City. Step 4: Mumbai is the financial and entertainment capital of India rather than an electronics focussed city. Step 5: Based on these associations, conclude that Bengaluru best fits the nickname Electronic City of India.

Verification / Alternative check:
Economic geography notes and general knowledge books frequently mention Bengaluru as both the Silicon Valley of India and as the location of the Electronic City industrial park. Articles describing major IT corridors in India also highlight Electronic City in Bengaluru as one of the earliest and largest dedicated technology hubs. This consistent usage confirms that the answer expected in exams is Bengaluru.

Why Other Options Are Wrong:
Hyderabad is an important IT centre but is more commonly associated with terms like Cyberabad and is not usually called the Electronic City of India. Mumbai is known for finance, stock exchanges and the film industry, not for a concentrated electronics industrial zone with this nickname. Gurgaon is a major corporate and outsourcing hub near Delhi but is not widely labelled as Electronic City in standard GK references.

Common Pitfalls:
Because several Indian cities have strong IT sectors, students sometimes confuse their nicknames. A simple way to remember is that Bengaluru has the specific industrial area named Electronic City, which gives rise to the broader nickname. Linking the city with both Silicon Valley of India and Electronic City helps reinforce the association.

Final Answer:
The city popularly known as the Electronic City of India is Bengaluru.
