Which of the following statements is correct about the Sokoto plains?

The correct statement about the Sokoto plains is that it is not an area of inland drainage. The Sokoto plains are a large expanse of low-lying flat land in northwestern Nigeria that is drained by the Sokoto River and its tributaries, including the Rima River. This means that the area is not an inland drainage area, as the water from the rivers flows outwards towards the Atlantic Ocean. The other statements are incorrect. The Sokoto plains do not lie in the middle of the country nor do they border the Rivers Benue and Niger. They are not a pear-shaped upland area, as they are actually low-lying plains. They also do not consist of the basement complex rocks, which are found in other parts of Nigeria. Finally, the Sokoto plains are not dissected by rift valleys and plateaus, as they are relatively flat and do not have major topographical features.
