The statement that inner scopes can access outer scope variables is true and aligns with the rules of variable scope in C programming. In C, when a variable is defined in an outer scope, it can be accessed by inner scopes, including nested functions or blocks. This is known as lexical scoping, where the scope of a variable is determined by its position within the source code.

For example, if a variable is declared in a function, any nested blocks (like loops or conditional statements) within that function can access the variable. This allows for more flexible use of variables as they can hold significant values in outer scopes while still being usable in more specific, inner scopes.

This characteristic is crucial for managing variables effectively as it minimizes the need to redefine variables in inner scopes, thus conserving memory and reducing redundancy. It also promotes better organization of code since inner blocks can utilize the context set by outer blocks without duplication.
