Explanation:
The Great plains are the best continental region for farming. Plains are rich in alluvial soils, these soils are formed by deposition of soil by the river over time. These soils are very fertile because they accumulate the runoff minerals from soils and make them nutritionally rich.
The availability of water in plains is more. These plains are covered with grasslands and steppes. It is extended into the Canadian region.

The correct answer is B. Igneous and metamorphic.
Metallic ores are produced by igneous and metamorphic processes.
Deposits of ore are formed by lateral secretion which is formed during shearing by metamorphic reaction and they liberate some constituents of minerals.
For example, carbonate, oxides, sulfides, gold, and quartz.
The most common metal ore is aluminium which is found in silicate ores which are known as type of clay.
There are different kinds of rocks. Sedimentary rocks found high in the Himalayan Mountains indicate that The Earth's crust that formed these mountains was once covered with an ocean.
The Higher Himalaya is known to be the framework of the Himalayan mountains. It is said to be composed of 10-20 km-thick metamorphic rocks (e.g. schist and gneiss) and granites.
They are found at altitudes of 3000 m to about 8000 m. These rocks are known to be of Proterozoic-Cambrian age called about 2,000-500 Ma.
