Concept:A flowchart uses connected symbols to show the sequence and logical flow of a process.
Explanation:In flowcharting, every symbol is joined with arrows called flowlines.
These arrows indicate the logical order in which the steps are executed.
Option A correctly states that all boxes are connected with arrows to show their logical connection.
Option B is incorrect because on-page connectors are used only to avoid long or crossing lines, not to join all process boxes.
Option C is incorrect because a flowchart ends with an end or terminal symbol, not with a decision box.
Option D is incorrect because the flow of control normally moves from top to bottom or from left to right, not always from bottom to top.
Therefore, the correct statement about flowcharting rules is Option A.
Answer:A. All boxes of flowcharts are connected with arrows to show the logical connection between them.
