Ray's Shipment of Materials Hit Every Red Light and Traffic

Ray's shipment of materials hit every red light and traffic jam on the way to the site.Upon arrival,half of the material was judged defective,necessitating a trip back to the supplier,and then the same arduous journey back to the site once the new materials were loaded.Traffic was a little better on the second round but the flat tire and subsequent repair caused as much if not more delay than the first trip.In the final analysis:

A) the project activity of Material Delivery was pretty close to the optimistic estimate.
B) the project activity of Material Delivery was pretty close to the most likely estimate.
C) the project activity of Material Delivery had a much higher variance than anticipated.
D) the project activity of Material Delivery was pretty close to the pessimistic estimate.
