The correct answer is option 1, South Africa. South Africa is not a major producer of natural gas in the world.
Option 2, Norway, is a major producer of natural gas. Norway is known for its substantial natural gas reserves and is one of the largest exporters of natural gas in the world.
Option 3, United Kingdom, is also a major producer of natural gas. The UK has significant natural gas reserves in the North Sea and is one of the top producers in Europe.
Option 4, Russia, is one of the largest producers and exporters of natural gas in the world. Russia has vast natural gas reserves, particularly in Siberia, and is a key player in the global natural gas market.
Therefore, option 1 - South Africa is the correct answer as it is not a major producer of natural gas compared to the other options.
