The code you've provided primarily demonstrates Iteration. Let's break it down:

  1. Iteration: The part of the code that iterates over the colourList using a FOR loop is the primary example of iteration. This allows the program to repeat a block of code (in this case, printing each colour) for each item in the list.

  2. Sequencing: This refers to the order in which the statements are executed. The program first prints the message "The rainbow colours are: " and then starts to iterate through the list. This linear execution of statements is an example of sequencing.

  3. Selection: This construct is not explicitly used in your code. Selection usually refers to decision-making structures like if statements that allow a program to execute certain blocks of code based on conditions. Since your example doesn't include any conditional statements, selection is not represented here.

So, in summary:

  • The provided code demonstrates Iteration (through the FOR loop), and it includes Sequencing (the order of execution of statements), but does not include Selection.
