Which diagram symbol resembles a diamond and marks a point where a decision is made?

• A. Decision Symbol
• B. Processing Symbol
• C. Input/Output Symbol
• D. Storage Location

Answer: (A)

In flowchart notation, the diamond shape marks a decision point where a condition is evaluated. At this juncture the flow splits into different paths based on the result (such as true/false or yes/no), guiding the next step accordingly. This is different from a rectangle, which represents a single processing action; a parallelogram, which shows input or output; or a storage symbol, which indicates data kept or retrieved. The diamond’s geometry visually signals that the next step depends on a test, making it the symbol used for decisions.
