Which of the following is the correct combination for wheat?
A. Genus: Triticum , Family: Anacardiaceae, Order: Poales, Class: Monocotyledonae
B. Genus: Triticum , Family: Poaceae, Order: Poales, Class: Dicotyledonae
C. Genus: Triticum , Family: Poaceae, Order: Sapindales, Class: Monocotyledonae
D. Genus: Triticum , Family: Poaceae, Order: Poales, Class: Monocotyledonae

Hint: The taxonomic classification is the process in which organisms are placed into a scientific category based on their similarities. The taxonomic classification is very complicated and involves many steps which take into account the genus and species and similarities between related species.

Complete step by step answer:
Option A: Wheat does not belong to the Anacardiaceae family.
Examples are cashew, mango, Peruvian pepper, and other plants in the Anacardiaceae family. As a result, this is the erroneous option.
Option B: Wheat does not belong to the Dicotyledonae class. Examples are Rose, oak, pea, and other plants in the Dicotyledonae class. As a result, this is the erroneous option.
Option C: Wheat does not belong to the Sapindales order. Sapindales plants include citrous, maples, rambutan, and others. As a result, this is the erroneous option.
Option D: Triticum is the genus name for wheat. Triticum is synonymous with free-threshing wheat. Poaceae, often called Gramineae, is a large and practically global grass family. It includes cereal grasses, and the flowers are typically tiny, enclosed by bracts, and arranged in an inflorescence. Wind pollinated flowers are found in the Order Poales (mostly).
The right answer is 'Genus Triticum, Family Poaceae, Order Poales, Class Monocotyledonae’.

Note: Wheat is an iconic cereal crop because it is one of the most important in world trade, irrespective of the production region. The wheat genus is in a taxonomic group called Triticum, with about ten species.
