The slack for any activity on the critical path will be A. negative. B. zero. C. positive. D. infinite.

The slack for any activity on the critical path will be zero.

Option: (B)

Explanation:

The critical path is characterized by complications of operations and intermingling of various factors. These factors in the critical path are of prime importance and are usually paid great attention to in order to avoid operation failures. Hence, the possibility of slack for any activity that is being conducted on the path that is critical for the operation is usually zero.
