The task is to iterate through a collection of a known size (the array) and perform an action on each element. A for loop is the most appropriate and idiomatic control structure for this purpose. It is specifically designed for iterating a fixed number of times, such as the length of an array, handling the initialization, condition check, and increment of a counter variable in a single, clear statement.

A. A while loop can be used, but it is less conventional for iterating over a known-size array and requires manual management of the counter variable.

B. Nested for loops are used for iterating over multi-dimensional data structures (e.g., a 2D array), which is unnecessary for this simple task.

C. if statements are used for conditional execution (branching), not for iteration or looping through a collection of elements.

This document defines the for statement as being "used to iterate over the elements of a sequence (such as a string, tuple or list) or other iterable object."
