The code you provided primarily demonstrates **iteration**.
Here's a breakdown of why it's categorized as iteration:
- **Iteration**: The code continuously repeats a block of code while a certain condition is true—in this case, while `timer` is greater than 0. This is achieved using a `WHILE` loop. Each time the loop runs, it prints "Carry on playing..." and decreases the `timer` by 1 until the condition fails (i.e., when the timer reaches 0).
**Selection** and **sequencing** are not applicable in this context because:
- **Selection** involves decision-making structures (like `if`, `else`, etc.) that choose between different paths of execution based on some condition.
- **Sequencing** refers to the execution of statements in a sequential order, which is indeed happening in the code, but since the primary focus is on the repeating behavior of the loop, it falls under iteration.
So, the correct classification for your provided code is **iteration**.
