The pseudocode below is an example of which control structure?

Question

Let's break down what's being asked and examine each answer option in turn.
Option a: 'Selection' — Selection structures involve choosing between alternatives, such as if-else or switch statements. The given pseudocode does not show any conditionals or branching decisions, so this option does not describe the code.
Option b: 'Repetition' — Repetition or iteration structures involve looping, where a block of code is executed multiple times (e.g., while or for loops). The sample shows a linear sequence of steps without any loop constructs, so this is not a match.
Option c: 'Loop' — This is another term for repetition/iteration. Since there is no looping mechanism (no repeats or exit conditions), this option is inaccurate for the provided code.
Option d: 'Sequence' — A sequence control structure executes statements one after another in a fixed order from beginning to end. The pseudocode depicted (Begin, A ← 5, B ← 2, C ← A * B, Print C, End) follows a straight line of operations with no branching or looping, which is characteristic of a sequence.
Therefore, the correct identification of the control structure demonstrated by the pseudocode is sequence. The explanation above highlights why the other control structures do not apply here and why sequence fits the given flow.
