Classical systems are a type of agricultural approach that allows for more than one kind of crop to be cultivated simultaneously which contributes to higher resource efficacy like sunlight, water, and curb pest infestation.Here is the understanding of what each answer means and why it’s wrongful or correct:Option A: This says that the corps seeking to co-exist in an intercrop system should have similar need for sunlight. This is not necessarily the case because different plants have different sunlight requirement and although can grow optimally in varying sunlight concentration. Option B: Says the corps should thrive on different sunlight intensity. This seems the natural deduction to dispute option A, which could be erred. But the general principle is that there should be complimenting which might explain difference in need as long as there no outright oppose in terms of starvation of sunlight for the other crops. Option C: this seems to recap the concept of compliment whether there is equality in demand for light or not. Any light capturing plant must not obstruct sunlight the other crops. Option D: seems also logical in the wild: plants keep distance from each to ensure competition for sunlight would be minimized as observed in forest trees. But here, the blunter segment of the statement is in stating a strict discrete distribution of crops where there claim edge on their leaf bearing section. Perhaps complex distribution exists where there no blanket shading of one plant by another. Nonetheless, the most applicable options are C & perhaps D if strictness of tan caste can be a bit softened.
