When sailing with the wind aft, a vessel may carry sails on both sides at the same time. Which is the proper term for this configuration?

Correct Answer: Option D — Wing and wing

Carrying sails on opposite sides while running directly downwind is termed 'wing and wing'. This traditional seamanship configuration maximizes projected sail area perpendicular to the true wind vector, commonly utilizing a main boom on one side and a headsail boomed out opposite.
