What should be part of every flowchart? A. A decision symbol B. A single end point C. At least one end point D. At least one data input symbol

To determine what should be part of every flowchart, let's analyze the options given:

1. A decision symbol: While decision symbols (diamonds) are important for representing choices in a flowchart, not all flowcharts require them. For instance, simple linear processes may not have any decisions.

2. A single end point: Flowcharts can have multiple endpoints depending on the complexity of the process being represented. Thus, this is not a strict requirement for every flowchart.

3. At least one end point: Every flowchart must conclude the process it represents with at least one endpoint. This signifies the completion of the process.

4. At least one data input symbol: While data input symbols (parallelograms) are common, they are not mandatory in every flowchart. Some flowcharts might represent processes that do not require data input.

After analyzing each option, the key requirement for every flowchart is to have at least one endpoint to signify the conclusion of the process.

Final Answer

C. At least one end point
