A dummy activity is a fictional activity that does not require any time or resources to complete but helps maintain the precedence relationships between activities in a PERT network. It is used when there is a dependency between two activities that cannot be shown by a direct arrow link. By adding a dummy activity, we can ensure that the correct sequence of events is maintained in the network. Therefore, option B is the best choice. Options A, C, and D are not accurate because a dummy activity does not require any time or resources to complete, and it does not allow adding more starting or ending nodes.
