You have been given a project to construct a bridge. You have done the planning and the network diagram is drawn with following paths: First Path: Start -> A -> B -> C-> End, duration: 31 months. Second Path: Start ->D -> E ->F -> K->End, duration: 31 months.

Third Path: Start -> D -> B -> C -> End, duration: 26 months. Fourth Path: Start -> G ->H ->I ->L-> End, duration: 31 months. Fifth Path: Start -> G -> E ->F -> End, duration: 16 months With the following information on hand, you can conclude that:

(a) The project is very risky

(b) The project is less risky

(c) You will manage it easily since three paths have the same duration

(d) You will need to add buffers on some paths
