Project duration in calendar days is

D$.19$

A$.17$

B$.14$

C$.20$

The critical path is

A$.$ A$-$B$-$E$-$F

B$.A-B-D$

C$.$ A$-$C$-$E$-$F

D$.A-C-D$

The free float of activity $F$ in working days is

A$.$ Zero

B$.1$

C$.2$

D$.3$

The activity with Free Float $=0$ but Total Float $0$ is

A$.$ Activity $C$

B$.$ Activity D

C$.$ Activity E

D$.$ Activity $F$

The total float for activity $C$ in working days is

A$.$ Zero

B$.3$

C$.4$

D$.7$

If the last Saturday $($Oct$.19)$ is converted into a working day, the project will be completed on

A$.$ October $19$

B$.$ October $18$

C$.$ October $17$

D$.$ None of the above

A reviewer of the above$-$shown bar chart schedule suggests changing the duration of activity $E$ to $5$ days. If this change is implemented, the total float of activity $F$ will become

A$.$ Zero

B$.1$

C$.2$

D$.3$

With reference to the previous question $($if the duration of activity $E$ is changed to $5$ days$),$ the only activity with non$-$zero float would be

A$.$ Activity $F$

B$.$ Activity D

C$.$ Activity E

D$.$ Activity C
