A simple project listing of five activities and their respective time estimates are presented below: $$\begin{array} { | l | l | l | }
\hline \text { Activity } & \text { Immediate Predecessor } & \text { Time in Days } \
\hline \text { A } & \text { None } & 1 \
\hline \text { B } & \text { A } & 2 \
\hline \text { C } & \text { A } & 1 \
\hline \text { D } & \text { B and C } & 3 \
\hline \text { E } & \text { D } & 2 \
\hline
\end{array}$$
Using CPM,which activities make up the critical path?
A) A,C,D,E
B) A,B,D,E
C) A,C,B,D,E
D) A,D,E
E) None of the above

The critical path is the longest path through the network of activities, which in this case is A → B → D → E. Therefore, choices A, C, and D are incorrect as they all omit activity B. Choice E is incorrect as it suggests that there is no critical path.
