The correct spelling is C. Freight.
Freights are goods that are transported through trains, buses, trucks and the like.
Words like Freight are often misspelled, particularly when arranging the letter "e" and the letter "i". People usually remember the mnemonic "I before E, except after C. " But this word is an exception, because if the sound is that of a long "a", the arrangement is "ei." Like in neighbor, weight and reign.
