What does MARPOL stand for?

MARPOL stands for the International Convention for the Prevention of Pollution from Ships. It is primarily focused on preventing marine pollution by regulating the disposal of harmful substances and waste from ships into the ocean. Option B, "Marine Pollution," accurately reflects the main objective of MARPOL, which aims to protect the marine environment from pollution by ships. This convention has various annexes that address different types of pollutants, ensuring comprehensive measures are in place for various operational scenarios encountered at sea.

The other options do not correctly represent the purpose of MARPOL, as they suggest a more general approach to marine policies or practices that do not specifically address pollution prevention and environmental protection measures set forth by the convention.
