Which flowchart symbol is commonly used to depict a processing step (an action or operation)?

• A. Diamond
• B. Oval
• C. Rectangle
• D. Parallelogram

Answer: (C)

In flowcharts, the symbol used for a processing step is a rectangle. This shape represents an action that changes data or performs an operation, like calculating a value or updating a variable. The other shapes serve different purposes: a diamond indicates a decision that creates branches, an oval marks the start or end of the chart, and a parallelogram denotes input or output operations. So, the rectangle best fits the idea of a processing step, making it the right choice.
