B is wrong. There are some plants that can survive long periods of darkness. I wouldn't say C is right either. Take seaweed for example. It is kind of a plant, (I do not remember), but itt does attack itself to the sea floor. Not sure about A, could be right, but best chance would be D.

wouldn't the temperature of the water impact plant growth? I would also assume that ice build up would prevent sunlight from reaching plants
