Which of the following statements is true regarding nested loops?

Nested loops are defined as loops that exist within another loop. This structure allows the inner loop to execute multiple times for each iteration of the outer loop. For example, if you have an outer loop that iterates over a range of numbers and an inner loop that also iterates over a range, the inner loop will execute completely for each cycle of the outer loop. This can be particularly useful in scenarios such as iterating over multi-dimensional arrays or matrices, where you need to process each element of the structure.

The ability of loops to nest is fundamental to many algorithms, allowing for complex repetitive tasks and enabling the handling of more than one set of data at once. This feature exemplifies the power of programming constructs, enabling programmers to solve a wide variety of problems through a structured approach.

The other statements do not capture the nature of nested loops accurately and do not reflect their full capabilities or usage in programming. Nested loops do interact with each other through their iteration processes, are not limited solely to arrays, and can certainly include conditional statements, enhancing their functionality in algorithm design.
