Which of the following is applicable to 'PERT'?

A) It needs a grid to be plotted out.
B) It is also known as 'CPM'.
C) It can determine the longest anticipated single line of activity from start to finish.
D) It identifies the ordering of activities that would complete the project in the shortest possible time.

PERT (Program Evaluation and Review Technique) can determine the longest anticipated single line of activity from start to finish, which is also known as the critical path. Option A is incorrect as PERT does not necessarily require a grid to be plotted out - it can be represented using a network diagram. Option B is incorrect as CPM (Critical Path Method) is a different project management technique. Option D is incorrect as it refers to CPM, not PERT.
