Which of the following describes a storage location whose value can be modified during runtime?

A variable is a named storage location in memory whose value can be changed as the program runs. You assign an initial value and later update it, so the stored data mutates over time. For example, a variable x might start as 5 and later be set to 12 based on user input or calculations. An array, while it stores data, is a collection of multiple values rather than a single place that represents a changing value; you can modify its elements, but the concept described points to a single mutable storage location. A function is a block of code, not a place to store a changing value. A class defines a blueprint for objects and their fields and methods, not a standalone mutable storage location.
