The code you provided demonstrates **iteration**. Here's a breakdown of the three basic programming constructs:

1. **Sequence**: This refers to the execution of statements in a linear, step-by-step manner. Each line of code executes one after the other.

2. **Selection**: This involves making decisions in the code, typically using conditional statements (like `if`, `else`, etc.) to execute certain blocks of code based on conditions.

3. **Iteration**: This involves repeating a block of code multiple times, usually with a loop structure (like `while`, `for`, etc.).

The code snippet you provided uses a `while` loop to repeatedly print "Carry on playing..." until the `timer` is no longer greater than 0. Hence, the correct usage in your context is **iteration**.
