Which programming construct allows for iteration based on a collection of elements, rather than a condition?

The foreach loop is specifically designed for iterating over collections of elements, such as arrays or lists. This construct simplifies the process of traversing collections by abstracting the iteration logic, which allows developers to focus more on manipulating the elements rather than managing the index or condition.

In a foreach loop, you do not need to manually set up the loop variable or worry about the boundary conditions; the loop automatically iterates over each item in the collection until all items have been processed. This enhances code readability and reduces the potential for errors related to indexing, making it a preferred choice for scenarios where the entire collection needs to be accessed.

In contrast, the other options are more general iteration constructs that rely on a condition or index. While they can also be used to traverse collections, they do not inherently provide the same level of simplicity or clarity as the foreach loop when specifically dealing with collections of data.
