ANSWER AND EXPLANATION:
The correct answer is D
Explanation: The PERT technique is based on the assumption that the underlying data can be represented by a triangular distribution. This is another way of saying that PERT is using a three-point (triangular) estimation. Note: This question is intentionally a bit obscure. However, it is a valid question because you must expect to find "obscure" questions that are taken from sources other than the PMBOK® Guide on the real PMP Exam. If you come across a question on the exam where you ask yourself "How on earth could anyone know this?" then you need to make a selection and move on.
