The correct answer is - secondary economic activity.
The developing countries are trying to boost and develop their economies by developing the industry. They build lots of industrial facilities, factories, and instead of selling the raw materials to the more developed countries, they start to use the raw materials for their own purpose and manufacture them into products ready for the market. This production can include anything from creating steel from the iron ore, make juices from the fruits and vegetables, use the cotton for making clothes etc., so all in all making final products that directly end up on the market, thus making a bigger profit.

Answer:
D. Because there was more gas farther from the Sun. As the are out of the range
Explanation:
- Basically, due to the core acceleration mechanism, theory to the formation of gaseous objects that can pull the gas as farther away from the sun the impact of solar winds is quite less. There are low-pressure regions
- Unlike rocky planets that have a different atmosphere and gas giants don't have a well-defined surface there atmosphere simply becomes denser to the core which may also be in a liquid-like state thus not suitable for landing.
- There are four gaseous giants in our solar system such as Uranus, Neptune, Jupiter Saturn all have atmosphere covered with ice or gases and all are bigger as compared to terrestrial planets like earth thus they are called as Jovian planets.
- These Jovians attract large amounts of gas as their magnetic fields are stronger and huge size ad gas giants are known as metallic molecules of hydrogen and helium in core consisting of more than 50% of the planet masses.
