Answer : Option D
Explanation :
Guidelines for constructing Network Diagrams:
-Each activity is represented by only one arrow.
-An arrow can represent only one activity
-If two or more activities are identified with the same start & end events. Dummy activity / activities need to be introduced in the network
-Before an activity can be started all preceding activities must be completed
-The flow of diagram is from left to right.
-The arrows are not to the scale
-Arrows should be straight
-Unless absolutely unavoidable, arrows should not be crossed.
