India held its first ever global tourism mart, organised as a national level tourism trade event, in which Indian city?

Introduction / Context:
Tourism trade events are important platforms where tourism boards, travel companies, and other stakeholders come together to promote destinations and build partnerships. India organised its first ever global tourism mart to showcase the country as a major destination to international buyers. This question tests awareness of Indian tourism initiatives by asking in which city this inaugural global tourism mart was held.

Given Data / Assumptions:
- The event mentioned is the first ever global tourism mart organised by India.
- It was a major national and international tourism trade event.
- Four major Indian cities are listed as options: New Delhi, Hyderabad, Bengaluru, and Kolkata.
- Only one of these cities actually hosted the inaugural event.

Concept / Approach:
The approach is to recall news related to India Tourism Mart or similar events. The first such global tourism mart was held in the national capital, New Delhi, where the central government, industry partners, and international buyers gathered. Since many major national level conferences and trade shows are hosted in the capital, it is a logical and also factual choice. The other cities are important in their own right but were not the host of this specific first edition.

Step-by-Step Solution:
Step 1: Recognise that the phrase "first ever global tourism mart" refers to a significant, centrally coordinated tourism event. Step 2: Recall that high profile national tourism events are often organised in New Delhi due to its status as the capital and its infrastructure for major conferences. Step 3: Match this recollection with the options available. Step 4: Confirm from memory of current affairs that the inaugural India Tourism Mart, which was promoted as a global tourism mart, took place in New Delhi. Step 5: Select New Delhi as the correct answer.

Verification / Alternative check:
If a candidate is unsure, elimination can help. Bengaluru and Hyderabad are major technology and business hubs, and Kolkata is historically significant, but central government ministries and national tourism bodies most frequently choose New Delhi for first time high level events. News coverage of the first India Tourism Mart highlighted the event as being inaugurated in New Delhi, further confirming this answer.

Why Other Options Are Wrong:
Hyderabad: Although it hosts many conferences, it was not the city for this particular first global tourism mart organised by India.
Bengaluru: A major technology hub, but it did not host the inaugural national level global tourism mart mentioned here.
Kolkata: An important eastern metropolis, but it was not chosen as the venue for the first edition of this specific tourism mart.

Common Pitfalls:
A common mistake is to treat all big cities as equally likely without remembering the central role of New Delhi in hosting national launch events. Another error is to mix up different tourism or trade exhibitions held in various cities. Keeping a mental note that the first large national level tourism mart event of this kind was held in New Delhi helps in avoiding confusion when similar questions appear.

Final Answer:
Thus, India held its first ever global tourism mart in New Delhi.
