Which international airport in India has bagged the National Award for Excellence in Energy Management for its efforts in efficient energy use and conservation?

Introduction / Context:
This question relates to awards for energy management and conservation, focusing on an Indian international airport that received the National Award for Excellence in Energy Management. Airports are large energy consumers, and recognition is given to those that implement innovative measures in energy efficiency. The question tests whether the learner knows which airport has been publicly recognised for such efforts.

Given Data / Assumptions:
- The award is the National Award for Excellence in Energy Management.
- It is given for efficient and innovative energy use and conservation.
- The recipient is an international airport in India.
- Options list four major Indian airports: New Delhi, Lucknow, Hyderabad and Mumbai.
- We assume that one of these is officially reported as having received this specific award.

Concept / Approach:
Some airports in India have invested significantly in energy efficient lighting, building design and renewable power. Hyderabad International Airport has been highlighted as a leader in environmental and energy management, receiving the National Award for Excellence in Energy Management from recognised industry bodies. The approach is therefore to associate this award with the correct airport among the options.

Step-by-Step Solution:
Step 1: Recall that Hyderabad International Airport has won several awards related to environmental performance and energy efficiency. Step 2: Recognise that the National Award for Excellence in Energy Management acknowledges such initiatives and has been given to Hyderabad for its achievements. Step 3: Look at the options and pick out Hyderabad as option C. Step 4: Understand that while New Delhi and Mumbai airports are large and modern, the specific award mentioned in this question is closely associated with Hyderabad. Step 5: Select Hyderabad as the correct answer.

Verification / Alternative check:
Press releases and industry reports on energy efficiency in infrastructure cite Hyderabad International Airport as a recipient of the National Award for Excellence in Energy Management. Details include installation of efficient lighting systems, building management technologies and partial use of renewable energy. These documents verify that Hyderabad fits the description given in the question, rather than the other listed airports.

Why Other Options Are Wrong:
New Delhi airport is a major hub with many awards, but the specific award for Excellence in Energy Management in this context is attributed to Hyderabad in common GK references.
Lucknow airport is smaller and is not typically named as the recipient of this national level energy management award in standard exam material.
Mumbai airport is also a large international airport but is not the primary example cited for this particular award in competitive exam general knowledge sources.

Common Pitfalls:
Candidates often assume that the largest or most famous airport must be the correct answer and may guess New Delhi or Mumbai based purely on prominence. Another mistake is not following current affairs related to infrastructure and sustainability, which means they miss specific recognition of airports like Hyderabad. Regularly reading news about awards in environmental and energy fields helps avoid such guesswork.

Final Answer:
The international airport that bagged the National Award for Excellence in Energy Management is Hyderabad.
