Comcorp Shipping Clerk: Last week, no shipments of building supplies were sent out on friday. The five specially ordered shipments sent out last week were sent out on Thursday, and each of those specially ordered shipments consisted entirely of building supplies. Four shipments were sent to Truax Construction last week, none of which consisted of building supplies.

If the shipping clerk's statements are true, which of the following must also be true?

A. All of Comcorp's shipments of building supplies last week were specially ordered.
B. None of Comcorp's shipments sent on friday of last week was sent to Truax Construction.
C. None of the shipments sent by Comcorp by Truax Construction last week was specially ordered.
D. None of Comcorp's shipments sent on thursday of last week was sent to Truax Construction.
E. All of Comcorp's shipments of building supplies last week were sent out on thursday.

========================

Friday - no Building supply
5 specially ordered + thursday + all building supply
4 to Traux + No building supply

a- Yes or No - All specially ordered - incorrect
b - only building supply were not sent on Friday , other things could be sent to Truax - means four could be sent on Friday- incorrect
c - Non building supply were sent to Truax - and only building supply were specially ordered hence - True
d - could be sent
e - could be sent / or not
