Explanation:
Statement (I): A Dummy is an activity in the network.
- This statement is true. In project management, a dummy activity is an artificial activity inserted into a project network to maintain logic relationships between other activities.
Statement (II): A Dummy is a representation in the network requiring neither time nor resources.
- This statement is also true. Dummies do not require any time or resources to complete as they are simply used to represent logical relationships between activities.
Therefore, both Statement (I) and Statement (II) are individually true, but Statement (II) is NOT the correct explanation of Statement (I). While Statement (II) provides additional information about dummies, it does not explain why they are used in project networks. Dummies are primarily used to maintain the precedence relationships between activities in a network diagram.

Dummy activity:
An activity that neither requires time nor any other resources is called dummy activity. It is represented by a dotted line in a network. These are required in any network to establish the grammatical and logical relationships between different activities.
Note:
A dummy activity is used to establish the uniqueness in the network i.e. if two or more activities start from a single node and terminated to the same node then dummies are used to establish the grammatical relationship between these two activities. Refer the following figure:
In Fig I- Activity A and B are starting from node 1 and terminating to same node 2 which violates the network rules. To correct this we introduced a dummy activity between node 2 and node 3 (see fig II).
