Answer & Explanation
The correct answer is Option B: Regulations are not yet universally enforced by every minor state, but many countries have adopted strict, stringent domestic rules for territorial waters.
While international sewage regulations (Annex IV) have become stricter, global enforcement remains dependent on national adoption and port state requirements. Many jurisdictions impose additional stringent regulations within their territorial waters for sewage treatment and discharge.
