Which mountaineer became the world's youngest person to climb the Seven Summits and the Seven Volcanic Summits?

Introduction / Context:
Modern mountaineering records often involve combinations of extreme challenges, such as climbing the highest peak on each continent, known as the Seven Summits, and separately the Seven Volcanic Summits, the highest volcanoes on each continent. This question focuses on the person recognised as the youngest to complete both sets. Being aware of such records, particularly when an Indian climber is involved, is important for competitive exams that test updated general knowledge.

Given Data / Assumptions:

• The record is for the world's youngest person to climb Seven Summits and Seven Volcanic Summits.
• Options include historical mountaineers like Edmund Hillary, Apa Sherpa, Peter Habeler, Reinhold Messner, and Satyarup Siddhanta.
• We assume awareness of recent Indian achievements in adventure sports.

Concept / Approach:
The approach is to distinguish between classic mountaineering pioneers and modern record holders. Edmund Hillary and Tenzing Norgay are known for the first ascent of Mount Everest. Reinhold Messner is renowned for climbing all fourteen eight thousand metre peaks. Apa Sherpa holds records for multiple Everest ascents. Peter Habeler is famous for climbing Everest without supplemental oxygen with Messner. However, the specific combined record of Seven Summits and Seven Volcanic Summits at the youngest age is credited to Indian climber Satyarup Siddhanta.

Step-by-Step Solution:
Step 1: Identify that this is a very recent record involving Seven Summits and Seven Volcanic Summits together.Step 2: Recall that news reports highlighted Satyarup Siddhanta, an Indian mountaineer, for achieving this feat and being recognised by Guinness World Records.Step 3: Compare with Edmund Hillary, whose achievement was specific to Everest, not all these summits combined.Step 4: Note that Apa Sherpa is known for repeated Everest climbs and does not hold this particular combined record.Step 5: Recognise that Peter Habeler and Reinhold Messner are associated with high altitude climbs and innovations like climbing without supplemental oxygen, not this Seven plus Seven record.Step 6: Conclude that Satyarup Siddhanta fits the description exactly.

Verification / Alternative check:

Why Other Options Are Wrong:
Edmund Hillary is historically important but is not associated with the Seven Summits plus Seven Volcanic Summits record.Apa Sherpa is known for many Everest ascents, not for this specific global record.Peter Habeler is remembered for pioneering climbs without oxygen, not for completing both sets of summits.Reinhold Messner, while a legendary mountaineer, is famous for all fourteen eight thousand metre peaks and solo ascents, not this particular challenge.

Common Pitfalls:
A common error is to pick a big historical name like Edmund Hillary or Messner simply because they are familiar. Another mistake is to assume that famous Everest specialists like Apa Sherpa automatically hold all mountaineering records. To avoid such confusion, pay attention to the exact wording of the record and recall which recent Indian name has been newsworthy for this very challenge.

Final Answer:
The correct answer is Satyarup Siddhanta.
