Big Inch, a famous pipeline which carries petroleum from the oil wells, is located in which one of the following countries?

The correct option is U.S.A.

Explanation:
The Big Inch is a famous petroleum pipeline system located in the United States of America (U.S.A.). It was constructed during World War II (between 1942 and 1944) as an emergency war measure to transport crude oil from the oil fields of Texas to the eastern seaboard (specifically New Jersey and Pennsylvania).
Before its construction, oil was primarily transported by tankers, which were highly vulnerable to German submarine attacks. The pipeline provided a secure, overland route to ensure a steady supply of oil for the war effort. Because it connects the oil wells of the Gulf Coast region in the U.S.A. to the industrial northeast of the same country, the correct country is the U.S.A.
