The option that contains an independent clause is the last example - While the team made their play, the frenzied crowd cheered them to victory. The independent clause here would be <em>the frenzied crowd cheered them to victory. </em>
It shouod be written in the writers point of view
<span>Carbon is stored inside plants. When deforestation occurs or any other natural clearing of land, the carbon cycle is changed due to plants being removed that would have captured the CO2 and changed it to oxygen and also by the removal of large plants that store carbon being replaced with either small crops or concrete that do not store carbon.
In nature, fossil fuels release carbon very slowly over time, humans burn it at a much greater rate due to dependence on it, and burning fossil fuels emits a lot of CO2 into the atmosphere.</span>

Quatrain = quadruple = 4 lines
Sestet = 6 lines
Octave = octagon = 8 lines
Thats how I try to remember it.
