Correct Answer - Option 3 : Normal time
Explanation:
Direct Project cost:
(i) It is the cost that is directly dependent on the amount of resources involved for the completion of activities. It includes labour, materials, plants, and machining.
(ii) To get the same work done in less time, we have to increases the amount of labor, equipment, and time-saving material that too at extra charges which simply means increases indirect cost.
(iii) The project has the highest cost corresponding to the crash duration and has normal cost corresponding to the normal duration.
Normal time:
(i) Normal time is the standard time that an estimator would usually allow for an activity.
(ii) It is the time with which direct cost does not reduce with the increase in time.
Crash time:
(i) Crash time is the minimum possible time in which an activity can be completed, by employing extra resources.
(ii) Crash time is that time, beyond which the activity cannot be shortened by an amount of increases in the resources.
