Which statement best describes an algorithm?

• A. A plan of actions executed by a computer in a fixed order
• B. A graphical model of data
• C. A step-by-step set of instructions for solving a problem by a computer
• D. A random list of operations

Answer: (C)

An algorithm is a precise, finite set of steps that takes input and produces output, guiding a computer to solve a specific problem. The strength of this description lies in the step-by-step nature that you can follow and execute, including any decisions or loops needed to handle different data. That’s why describing it as a step-by-step set of instructions for solving a problem by a computer best captures what an algorithm is. Graphical models of data represent structures or diagrams used to organize information, not the procedure for solving a problem. A plan of actions in a fixed order can be limiting because many algorithms rely on decisions and repetitions rather than a single, unchanging sequence. A random list of operations lacks the purpose and reproducibility that define an algorithm.
