Concept:Pipeline transportation moves liquids or gases through fixed pipes between specific points.
Explanation:It is used to carry products such as crude oil, water, and natural gas.
Its main disadvantage is that it lacks flexibility.
A pipeline can only operate between fixed terminals and cannot easily be redirected.
This makes it limited in the number of places it can serve.
That major drawback is best described as a limitation in scope.
High construction or maintenance costs are also challenges, but they are not the major disadvantage.
Vulnerability to climate changes is not a typical problem for this mode.
Answer:C. Limitation in scope.
