By definition, a project
By definition, a project cannot be completed earlier than the duration of its critical path. Here, the required reduction is 3 weeks. For reducing the project duration by 3 weeks, we need to shorten the critical path by 3 weeks. Hence the new critical path - reduced by appropriate means - is of 20 weeks, i.e. it decreases by 3 weeks.
Hence choice 2.
Thanks.
