A project has the precedence requirements and activity durations shown in the table.After he draws the network,the project manager decides to represent a few activities by a hammock activity.Which is a legitimate hammock activity for this project? $$\begin{array} { | l | l | l | }
\hline & \text { Time } & \text { Predecessor } \
\hline \mathrm { A } & 7 & \
\hline \mathrm { B } & 8 & \mathrm {~A} \
\hline \mathrm { C } & 13 & \mathrm {~A} \
\hline \mathrm { D } & 8 & \mathrm {~A} \
\hline \mathrm { E } & 7 & \mathrm {~B} \
\hline \mathrm { F } & 6 & \mathrm { C } \
\hline \mathrm { G } & 6 & \mathrm { D } \
\hline \mathrm { H } & 11 & \mathrm { E } \
\hline \mathrm { I } & 12 & \mathrm { G } \
\hline \mathrm { T } & 14 & \mathrm { H } , \mathrm { F } , \mathrm { I } \

To create a hammock activity, we need to identify a group of activities that are not directly related to each other but are related to a common goal or milestone. In this project, the only activity that has three different predecessors is activity T. Therefore, we can create a hammock activity by combining activities B, E, and H, which are the direct predecessors of T. These activities are not directly related to each other but are related to activity T, which represents the milestone of the project completion. Therefore, choice B is the best option.
