Answer 1

Answer:

A. Imaginary

A dummy activity is an imaginary activity used on network diagrams to show the dependency, logic, or relationship of one activity over another. It does not consume any time or resources and is used when two or more activities have the same head and tail events. It is an alternative to an existing pattern and is not a true activity.
