Answer: a) Fuel Connector's place of business.
Explanation:
Since Go-Flo is expected to pick up the goods from Fuel Connector Products, Inc., therefore, Go-Flo should pick up the the hose couplings and fittings from Fuel Connector's office. Also, since the contract does not specify a place so its only logical that Go-Flo would have to go to Fuel Connector's place of business.
