Identify the control structure: The control structure that occurs when each block is executed one after the other.

Question

To identify the control structure described, we examine what each option implies in terms of execution order.
Option a: Repetition. Repetition refers to looping constructs where a block of code runs multiple times, typically until a condition is met. This is not about documents executing one after another, but about repeating a block.
Option b: Sequence. Sequence is the straightforward flow where statements or blocks execute in a fixed, linear order, one after the other, without branching or looping. This matches the description of blocks being executed in order.
Option c: Component. In programming, a component generally denotes a modular part of a system or program, not a specific execution order or control flow. It is not about the order in which blocks run.
Option d: Selection. Selection involves making a choice between different paths (like if/else), where the program may skip some blocks based on a condition. This is the opposite of executing blocks one after the other in a single, fixed sequence.
Thus, analyzing the nature of each option shows that only the sequence option describes executing blocks in a strict, linear order, one after another, with no repetition or branching.
