Here is a CPM network with activity times in weeks:

A network diagram flowchart. The flows are as follows. A $(7),$ B $(5),$ C $(6),$ and D $(6).$ A $(7),$ E $(4),$ G $(3),$ C $(6),$ and D $(6).$ A $(7),$ E $(4),$ F $(8),$ and D $(6).$

Determine the critical path.

multiple choice

A$-$B$-$C$-$D

A$-$E$-$G$-$C$-$D

A$-$E$-$F$-$D

How many weeks will the project take to complete?
