Difficulty: Easy
Choose an option
-
AEach activity is represented by one and only one arrow in the network
-
BDangling (unconnected ends) must be avoided in the network diagram
-
CA dummy activity consumes no time and no resources
-
DAll of the above
Answer
Correct Answer: All of the above
Explanation
Guidelines explained• One arrow per activity avoids duplication and ambiguity.• Avoid dangling ends; every activity must start/end at well-defined events.• Dummy activities exist only to maintain logic; they have zero duration and no resource use.
Final AnswerAll of the above.
