I think it is E.
There is only confusion between D & E.
The premise states that
1."All of the shipments on Friday were building supplies"
2. 3 out of 4 sent to Turox were building supplies.
It may or may not be true that the 3 out of 5 building suppiles shipped on Friday were sent to Turox.
But it is definitely true that one of the shipments sent to Turox was not building suppiles and that must have been sent before Friday!! ('coz no shipment that was not part of building materials was sent on Friday)
