The correct answer is B. Warehouse
Step-by-step explanation:
In grammar, for a word to correctly fit in a sentence the word needs to match with the meaning suggested by the sentence and besides this, it needs to be correctly written or spelled. In the case of the sentence provided "There has been a problem at the ________, so your shipment will be delayed" this sentence suggests the word that missing is a place were shipment occur and therefore a place in which shipments can be delayed. According to these clues, the best word for filling the blank is "warehouse" as this word refers to a building in which merchandise is stored and also, a place where shipments occur. Also, other options sound and look similar to "warehouse" but are not spelled or written correctly and therefore other options are incorrect.
