Which Python statement is used to stop the loop when certain conditions are met?

• A. continue
• B. break
• C. stop
• D. end

Answer: (B)

The statement used to stop a loop when certain conditions are met is the break statement. This command immediately terminates the nearest enclosing loop, whether it's a for loop or a while loop, and control is transferred to the statement that follows the loop. When a break statement is executed, the loop ends regardless of whether the loop's condition is still true or if there are still more items to be iterated over. This is particularly useful in scenarios where you want to exit a loop early based on a specific condition, enhancing the flow and efficiency of your code. For example, if a loop is searching for a specific element in a list, the break statement allows you to exit the loop as soon as that element is found, avoiding unnecessary iterations. This can significantly improve performance, especially in larger datasets. Other options such as continue, stop, and end do not serve the same purpose. The continue statement is used to skip the current iteration and proceed to the next iteration of the loop, while stop and end are not valid keywords in Python for controlling loop behavior.
