Which statement is true about a variable?

The statement that a variable can reference different values during program execution is true because variables are designed to store data that can be updated or changed throughout the lifecycle of a program. For instance, a variable may initially hold a value, and as the program executes, you may assign it a new value based on user input, calculations, or other conditions. This dynamic capability allows programmers to write flexible and efficient code that can respond to varying conditions and requirements as the program runs.

In programming, this ability to update the value of a variable is fundamental, allowing for the representation of changing states and making it essential for operations like loops, iterations, and conditional logic.
