Is it true that international regulations concerning pollution by oil are contained in Annex I?

International regulations concerning pollution by oil are indeed contained in Annex I of the MARPOL Convention, which stands for the International Convention for the Prevention of Pollution from Ships. This annex specifically addresses the prevention of pollution by oil from operational and accidental discharges. It includes regulations to manage the discharge of oil from tankers and other ships, ensuring that they carry out their operations in a way that minimizes the risk of oil spills into the marine environment.

The regulations established in Annex I include requirements for the design and construction of oil tankers, training for crew members, and procedures for managing oil waste and discharges. Compliance with these regulations is crucial for protecting the marine ecosystem from the harmful effects of oil pollution.

In contrast, the other options might suggest that the statement could be false, only partially true, or uncertain, which does not align with the established understanding of MARPOL Annex I. This annex is specifically focused on oil pollution, making the statement definitively true.
