Consider the following data for a project:

$\backslash$table$[[$Activity$,\backslash$table$[[$Activity Time$],[($days$)]],\backslash$table$[[$Immediate$],[$Predecessor$($s$)]]],[$A$,2,-],[$B$,$A$,$A$],[$C$,5,$A$],[$D$,2,$B$],[$E$,1,$B$],[$F$,8,$B$,$ C$],[$G$,3,$D$,$ E$],[$H$,8,$F$],[$I$,4,$F$],[$J$,7,$G$,$ H$,$ I$]]$

a$.$ Draw the AON network diagram $($with ES$,$ EF$,$ LS$,$ LF$,$ and Slack time$)$

b$.$ Identify all paths in this project and their durations

c$.$ Determine the project's critical path and duration
