Hint: Rice is the seed of the grass type Oryza glaberrima (African rice) or Oryza sativa (Asian rice). As a cereal grain, it is the most extensively disbursed staple food for a huge part of the world's human population, particularly in Asia and Africa.

Complete step by step solution:
Rice, a monocotyledon, is usually cultivated as a yearly plant, though in tropical areas it can endure as a recurrent and can harvest a ratoon crop for up to 30 years. Rice cultivation is compatible with nations and areas with little employment expenses and high rainfall, as it is labour-exhaustive to grow and necessitates plenty of water. Though, rice can be cultivated almost anyplace, even on a precipitous hill or mountain expanse with the use of water-regulatory veranda arrangements. Though its parent species are innate to Asia and specific parts of Africa, centuries of business and exportation have made it ordinary in numerous cultures internationally. The conventional system for growing rice is submerging the fields while, or after, situating the young seedlings. This meek process needs sound irrigation preparation but decreases the growth of less healthy weed and pest plants that have no flooded progress state, and discourages pests. While submerging is not compulsory for the farming of rice, all additional approaches of irrigation need higher determination in weed and pest control throughout progress stages and a dissimilar method for manuring the soil.

Thus, option (D) is correct.

Note: Rice plays an imperative role in specific religions and prevalent principles. In numerous cultures, families will strew rice throughout or towards the end of a wedding ritual in front of the bride and groom.
