Answer:
The correct answer would be Option C, Multipurpose Trees.
Explanation:
With the advancement in industries and other areas of technology, the rural areas have become so much polluted. So the sustainability of the rural areas is doubtful. The air in the rural areas have become polluted and needs measures to prevent it from harmful consequences of the industrial advancements. Along with industries, the air pollution is also added through vehicles discharge, waste disposal, etc also contribute towards the non sustainability of the rural areas. So to overcome all these problems, the best solution is to grow the multipurpose trees in the rural areas as much as possible to increase the sustainability of these areas. With the plantation of trees, the problem of pollution will be controlled and thus make these areas sustainable.
One big reason for this is because individuals of the same species often have to fight over shared resources (this means shared food and shared environment).
Because they fight over a limited amount of space and food, competition between individuals within one species can be present and very tough.
On the other hand, having members of different species also possibly means different territories and different food sources. A lion has no quarrel with dolphins, while it can have a lot of fights with lions from different prides (large group of lions).
I believe that the most logical explanation for this is that the right primary bronchus is wider than the left one (and the right lung is larger than the left lung), therefore the right lung receives slightly more carcinogenic cigarette smoke with each puff. In lung cancer. the cancer cells usually arise from the epithelium lining of large bronchus.
