The question is about understanding the meaning of verbs related to the process of moving goods. The correct answer is 'B. Unload', which means to remove goods from a vehicle. Option A, Load, means to put goods onto a vehicle, which is the opposite action. Option C, Ship, refers to sending goods by sea or by a ship, which is not the same as unloading. Option D, Transport, means to move goods from one place to another, which is a broader term and not specific to unloading.
