Answer is c. Natural gas.
Natural gas is a fossil fuel in liquid form that can be used as an energy source. It is found in subterranean reservoirs, often near oil deposits. It is non-renewable energy source. It takes very long time to renew. Natural gas is less pollutant as compared to coal and petroleum because when it's burned, it releases 25 % fewer greenhouse gases and pollutants. hydroelectric power, solar power and nuclear energy are renewable sources.
<span>The first desirable trait that is being engineered into our crops is sustainability. This means that crops are being bred to be able to grow in adverse conditions, ensuring the ability to sustain our food supply as humans. The second, are the alterations being genetically done to crops to eliminate the need for pesticides. By heightening the crops natural ability to eliminate and deter pests, there are higher yields and the elimination of pesticides seeping into and poisoning the human consumer. And, finally an ability to eliminate the need for traditional breeding in crops. By genetically replicating plants, we are eliminating the chance that the human race may "run out", of seeds, of starts, of the need for pollination. This basically ensures us an unlimited food supply, just in these three traits being bred into our crops.</span>
Aseptic technique is used to prevent microorganism to infect our body
One of the example of using aseptic technique is : wearing protective gloves when transferring bacteria an fungi to slides.
This action prevent those bacteria or fungi from transferring to our skin

Precipitation of water on the land surface in the hydrologic cycle leads directly to evaporation, filtration and run off
When water is release from clouds in the form of rain, sleet, hail, freezing rain, or snow precipitation happens. It is the main connection in the water cycle that gives for the transfer of atmospheric water to the Earth.
When it gets cold, the accumulated water inside the pipes freezes, expands and creates extreme pressure.
