The critical path has the longest path and consumes maximum time and maximum resource
So option B is correct.

1-2-3-5-6-7-8-9 = 24.
Bhargav said:   6 years ago
According to me, Option A is the correct answer.
Dhaval Chaudhary said:   6 years ago
A is correct answer 1-2-3-4-8-9.

CRITICAL Path:

A critical path consumes maximum resources. It is the longest path and consumes maximum time.

So the order of the network is 1-2-3-5-6-7-8-9.
Option B is correct.

Exactly @Neeraj. But according to the definition, critical path is the longest path and consumes maximum time. So, they are contradicting each other.
Neeraj said:   7 years ago
I think it is A.

Ref: RS Khurmi.

Critical path is one which takes more time to complete. So 1-2-5-6-7-8-9 is taking 22 days and other path 21 day so 1256789 should be the critical path.

Which takes minimum time? Explain in detail.

@ALL.

As an Industrial engineer, one of the function in a project is to obtain an optimal solution. However, I would suggest those against option B to study the algorithm of network diagram as regarding selecting the critical path(s).

The Crictical path can contain Dummy activities.

So answer B is right.
