Which statement best captures a core attribute or outcome of structured programming?

Introduction / Context:Structured programming is a paradigm that advocates the use of clear, block-structured control constructs (sequence, selection, iteration) and modular decomposition. Its primary characteristic is the functional modularization of a program into cohesive units with well-defined interfaces, which improves readability and maintainability.

Given Data / Assumptions:

• We are evaluating statements about programming style, not deployment topology.
• Modules should encapsulate single responsibilities.
• Error isolation improves when control flow is explicit and localized.

Concept / Approach:Functional modularization divides complex problems into smaller, testable units. This structure enables independent reasoning and simplifies debugging. Although localization of errors is a beneficial outcome, the defining attribute most directly associated with structured programming is its emphasis on modularization using disciplined control flow, rather than organizational decentralization or hardware centralization.

Step-by-Step Solution:

Verification / Alternative check:Canonical descriptions of structured programming reference modular design and the three control structures as the essence of the paradigm, confirming option A as the best capture.

Why Other Options Are Wrong:

Common Pitfalls:Confusing benefits (debuggability) with core practices (modularization) when characterizing a paradigm.

Final Answer:Functional modularization of code into cohesive units.
