What defines local variables in the system?

Local variables are defined as containers that store data values or states specific to a function or block of code. They exist within a defined scope, typically tied to the function or method in which they are declared. This scope outlines where the variable can be accessed or modified, ensuring that the data they store is relevant only within that context.

By design, local variables allow for dynamic data handling, meaning they can change values over time during the execution of a function. This adaptability is crucial for managing temporary states and facilitating operations like calculations, while also ensuring that they do not interfere with variables declared elsewhere, such as global variables.

The other choices might incorporate aspects related to variables but do not accurately capture the essence of what local variables represent. Static values imply immutability over time, global identifiers refer to the accessibility of variables across different parts of a program, and temporary storage units for actions do not specifically align with the concept of local variables, which are more fundamentally about scoped data representation within a function.
