According to Ahluwalia, the man who returns after climbing the mountains is a changed man. Let's explore why this answer is correct.

Change in Perspective and Attitude:
When a person climbs mountains, they are exposed to a challenging and unique environment. They have to face physical hardships, overcome obstacles, and push their limits. This experience can bring about a significant change in the person's perspective and attitude towards life. They learn to appreciate the beauty of nature, value their own strengths and abilities, and develop a sense of gratitude and humility.

Enhanced Confidence:
Climbing mountains requires courage, determination, and perseverance. When a person successfully completes such a feat, they gain immense confidence in their abilities. They realize that they are capable of achieving great things if they set their mind to it. This enhanced confidence can positively impact various aspects of their life, such as personal relationships, work, and decision-making.

Expanded Comfort Zone:
Mountain climbing pushes individuals out of their comfort zones and exposes them to unfamiliar situations. They have to adapt to changing weather conditions, navigate difficult terrains, and make quick decisions. By stepping out of their comfort zone, they not only grow as individuals but also develop resilience and adaptability. This expanded comfort zone allows them to approach challenges with a more open and positive mindset.

Appreciation for Nature:
Mountain climbers are often surrounded by breathtaking landscapes and natural wonders. They witness the beauty and magnificence of nature in its purest form. This experience can lead to a deep appreciation and respect for the environment. Climbers may become more mindful of their impact on the planet and take steps to protect and preserve it.

Increased Self-awareness:
Mountain climbing forces individuals to confront their fears, limitations, and weaknesses. It is a journey of self-discovery, where climbers learn more about themselves and their capabilities. They gain insights into their strengths, weaknesses, and areas for growth. This increased self-awareness can help them make better choices and lead a more fulfilling life.

In conclusion, according to Ahluwalia, the man who returns after climbing the mountains is a changed man. This transformation encompasses a shift in perspective, enhanced confidence, an expanded comfort zone, appreciation for nature, and increased self-awareness. By overcoming the challenges of mountain climbing, individuals can grow and evolve, making them a changed person.
