B) 2 and 3
C) 3 and 4
D) 1 and 4

Answer 1

Hint:
Monoculture cultivating is a type of farming that is based on growing just one type of a crop at one time on a particular field. Interestingly, a polyculture system assumes that a field is planted with at least two yields all at once. Numerous farmers plant just one harvest in a similar place quite a long time after year. This is what is known as monoculture crops. Supporters claim it is a more profitable way to farm than shifting crops around each year.

Complete solution:
Continuous monoculture, or mono-cropping, where farmers improve the same species year after year, can lead the way to the quicker build-up of pests and diseases, and then their unexpected stretch where a uniform crop is accessible to a pathogen. Monocultures of perennials, such as African palm oil, sugar cane, and pines, can lead to environmental problems.

Diversity can be enhanced both in time, as with a crop rotation or sequence, or in space, with a polyculture. The term "oligo culture" has been used to illustrate a crop revolution of just a few crops, as practised in several territories of the world. The idea of monoculture can also extend to (for example) discussions of variety in urban landscapes. Tea in Assam and coffee in Brazil both are cultivated that is based on growing just one type of a crop at one time on a particular field and these are the monoculture crops which provide immediate cash to the farmers.

Hence, the correct answer is option D.

Note:
Planting the same crop in the same place each year zaps nutrients from the earth and leaves soil weak and unable to support healthy plant growth. Because soil configuration and quality are so poor, farmers are obliged to use chemical fertilizers to motivate plant growth and fruit production. These fertilizers, in turn, disrupt the natural makeup of the soil and contribute further to nutrient depletion. Mono-cropping also establishes the spread of pests and diseases, which must be treated with yet more chemicals.
