Ship in a Canal

A 200-ton ship enters the lock of a canal. The fit between the sides of the lock and the ship is tight so that the weight of the water left in the lock after it closes is much less than 200 tons. Can the ship still float if the quantity of water left in the lock is much less than the ship's weight?

A) Yes, as long as the water gets up to the ship's waterline.

B) No, the ship touches bottom because it weighs more than the water in the lock

C) It depends or I can't tell.
