Question

River Mississippi drains in _________.
A) Canada
B) Africa
C) USA
D) India

Answer 1

Hint: The Mississippi River is the second-longest river in America and the chief river of the continent's second-largest drainage system, second only to the Hudson Bay drainage system. It about 2,350 miles in length.

Complete answer:
The Mississippi River is North America's longest river, draining an area of about 1.2 million square miles (3.1 million square kilometres) and its main tributaries, or about one-eighth of the continent.
The Mississippi River is completely within the boundaries of the United States. It begins in Minnesota's Lake Itasca and flows almost due south through the continental interior, receiving water from its main tributaries, the Missouri River (to the west) and the Ohio River (to the east), around halfway into its path to the Gulf of Mexico across a large delta southeast of New Orleans, a cumulative distance of 2,340 miles (3,766 km) from its source. The Mississippi River and its tributaries wash all or part of 31 U.S. states.
Now, when we look at the options countries like India, Africa and Canada are not part of US. Hence these options are incorrect.

Hence the correct option is (C) USA.

Note: For decades, the Mississippi River has served as a vital trading and transport corridor. It is also the cheapest mode of transportation between the Southeast United States. Several states depend on the Mississippi for hydroelectric power and water. As a result, the Mississippi River provides power and sanitation to a large number of residents in the United States, even without polluting the environment.
