Variable scope refers to the visibility and accessibility of a variable within a program. In Python, the order in which the interpreter looks for a variable follows the following sequence: local, instance, class, global. 
Therefore, the correct order of increasing scope is local, instance, class, global. 
Option C, local, instance, class, global, is the only option that reflects this order.
