Which paradigm uses three basic control structures to form highly structured units of code?

• A. Structured programming
• B. Loop structure
• C. Connector symbol
• D. Modular construction

Answer: (A)

The main idea here is organizing code with a small, reliable set of control constructs to build clear, structured programs. In structured programming, you express algorithms using three fundamental control structures: sequence (execute statements in order), selection (choose between branches with conditions), and iteration (repeat a block while a condition holds). Together, these allow you to form highly structured units of code without resorting to arbitrary jumps, making programs easier to read, reason about, and verify. The other options don’t capture this overarching approach: a loop structure is just a single construct, not a paradigm; a connector symbol isn’t a paradigm; and modular construction focuses on dividing code into modules, not on the trio of control structures that define structured programming.
