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.
The advantage of using passive or active solar systems was these systems release low amounts of carbon dioxide or other pollutants. Thus, Option C is the correct statement.
<h3>What is the benefit of using Passive or active solar systems?</h3>

Thus, Option C is the correct statement.

Answer: Anaerobic respiration or Fermentation
Explanation:
When we are engaged in intense physical activity such as running or riding a bike, the muscles need energy to function and they get this from aerobic respiration.
They will quickly run out of the oxygen required to sufficiently use aerobic respiration however and will turn to anaerobic respiration which can produce energy in the absence of oxygen.
As the body uses anaerobic respiration however, lactic acid is produced and builds up in the muscles. It is this lactic acid that leads to the muscles feeling sore.
