What is iteration in the context of algorithms?

The process of executing a specific part of an algorithm multiple times

A program has been developed to compute the sum of all elements with a value greater than 10 in a list of integers. Which of the following statements best describes how iteration may be used to in the program in this example? Options: The program will repeat the execution of a block of commands which test the value of an item and add it to a running total (if it is greater than 10) for each value in the list., The program will initiate a variable at the beginning and return the value of that variable at the end., The program will only execute a command which adds a value in the list to a running total if that value is greater than 10., The program will execute the commands for finding and adding the numbers in the order in which they appear in the program.

The program will repeat the execution of a block of commands which test the value of an item and add it to a running total (if it is greater than 10) for each value in the list.
