The Master of a vessel may tender a Notice of Readiness to the charterer when the vessel __________.

Correct Answer: Option C — is in all respects ready to load

A Notice of Readiness can only be validly tendered when the vessel is 'ready in all respects.' This means the holds are clean, inspected, and prepared, cargo gear is operational, and the vessel is legally and physically capable of receiving the specific cargo defined in the charter party agreement.
