Answer & Explanation Answer: B) As mathemetical analysis tools, they simply provide the dates that are posible, and do not consider resource pool limitations

Explanation:

Answer A is tempting because it is true by definition, but Answer B is correct because it properly answers the question, in that these techniques do not take into account resource pool constraints. Answer C is incorrect because it provides possible early and late start and finish dates, but not the actual schedules. Answer D is incorrect because none of the the three are simulation techniques.
