When slack of an activity is positive - the correct answer is - option [A]. It represents a situation where extra resources are available and the completion of project is not delayed.

When slack of an activity is positive means slack may be zero and higher. For this reason option C shall be also true. So that option D is correct.

When slack is zero at that time activity is critical. So correct is "A".

Slack or float is time by which any activity delay without delaying project completion.

Positive slack-----Ahead of schedule.

Negative slack------Behind the schedule.

Zero slack ---------On the schedule.

The correct answer is - option [A].

The correct answer is option [A].

When slack of an activity is positive - it represents a situation where extra resources are available and the completion of the project is not delayed.

When slack of an activity is negative- it represents that a program falls behind schedule and additional resources are required to complete the project in time.

When slack of an activity is zero - the activity is critical and any delay in its performance will delay the completion of the whole project.

I agree @Ashu.

Correct answer is (a). I too agree.

I too think the Correct answer is option A.

Answer A is correct.

Because positive slack never be behind the schedule or on the critical path.
