Which of the following describes an algorithm?

The description of an algorithm as a structured step-by-step procedure for problem-solving captures the essence of what an algorithm is fundamentally about. Algorithms are systematic approaches that consist of clearly defined steps, which can be followed to achieve a specific goal or to solve a particular problem. They are used in various fields such as computer science, mathematics, and data processing to develop solutions in a methodical way.

In contrast, a random sequence of transactions lacks the systematic structure that defines an algorithm. While promotional offers may be strategically planned, they do not represent a step-by-step method for problem-solving. Similarly, evaluating customer satisfaction is an important process but does not inherently involve following a defined algorithmic procedure. The clarity and organization in the definition of an algorithm emphasize its role as a tool for logic-based tasks, making the choice of structured, step-by-step procedures the most accurate representation.
