ANS:B - 1 and 4 only

Duration along the critical path defines the project duration. By proper planning it can be made as short as possible. Hence shorter duration is needed to complete the project in shortest time possible.

It is the maximum duration path hence the longest duration is permissible along the critical path in comparison to other path available from start to end.
