Which of the following Indian cities is popularly known as the City of Roses because of its planned gardens and rose lined avenues?

Introduction / Context:
Many Indian cities carry special nicknames that reflect their geography, architecture, main industries or cultural features. These nicknames are frequently tested in competitive exams as quick recall questions. The City of Roses is one such nickname, linked to a planned city known for its gardens and landscaped sectors where roses are widely cultivated and displayed. Identifying the correct city helps learners associate urban branding with specific locations in Indian geography.

Given Data / Assumptions:

- The nickname mentioned is City of Roses. - The options list Hyderabad, Kolkata, Mumbai and Chandigarh. - The question asks which one of these is popularly known by this nickname. - The focus is on standard general knowledge associations, not on informal local slogans.

Concept / Approach:
Chandigarh is a planned city designed by Le Corbusier and is famous for its orderly sectors, wide roads and well maintained gardens. Among its many green spaces, the Rose Garden is particularly famous and is often highlighted in tourism materials. As a result, Chandigarh has gained the popular nickname City of Roses in many general knowledge compilations. The approach is to recall that while other cities have different nicknames such as City of Joy for Kolkata, the rose based title is linked with Chandigarh.

Step-by-Step Solution:

Verification / Alternative check:
To verify, students can check lists of Indian city nicknames provided in general knowledge books and exam oriented websites. These lists usually match City of Roses with Chandigarh. Tourist brochures and official city descriptions also emphasise the presence of Asia s one of the largest rose gardens in Chandigarh, which reinforces the association between the city and roses. This repeated linkage confirms that Chandigarh is the city intended by the question.

Why Other Options Are Wrong:
Hyderabad is better known as the City of Pearls and for its information technology industry rather than for roses. Kolkata holds the nickname City of Joy, celebrating its cultural life. Mumbai is widely recognised as the Financial Capital of India and the hub of Bollywood cinema. None of these cities is commonly called the City of Roses in standard competitive exam material. None of the above is therefore incorrect because Chandigarh alone matches the nickname given in the question.

Common Pitfalls:
Some learners may mix up various city nicknames, especially when multiple floral names are involved, and may confuse City of Roses with other garden related titles. Others might guess Hyderabad or Mumbai simply because they are better known metros, without recalling the specific nickname. To avoid such confusion, it is helpful to make and revise a simple chart pairing each major nickname with its city, for example City of Joy with Kolkata, Pink City with Jaipur and City of Roses with Chandigarh.

Final Answer:
The Indian city popularly known as the City of Roses is Chandigarh.
