What is the lifesaving signal indicating "You are seen - Assistance will be given as soon as possible"?

Correct Answer: Option D — None of the above

Standard ground-air visual signals outlined in international search and rescue manuals dictate specific responses for aircraft acknowledging distress. Since none of the listed options accurately reflect the recognized surface-to-air or air-to-surface signals for 'You are seen,' 'None of the above' is correct.
