The correct answer is C. Ports of Call are defined as intermediate ports where ships stop primarily for refuelling, taking on provisions, or minor repairs during a voyage, rather than for loading or unloading cargo extensively.
The term ‘Ports of Call’ refers to transit points for ships on long journeys.
