Project can be shown using activity diagram as drawn below.
Critical Path for the project will be A -> D -> G and time for critical path is 16 days.
And by crashing the critical path it can be completed in 9 days. So total saving in days is 7 days.
However for calculating crashing cost –
Activity A,D,G need to be crashed along with only activity B, least cost required for crashing. Thus cost of crashing is 1670. Thus, Option D is correct Option.
