The offspring would be 50% BB and 50% Bb, so the plants would be tall. :)
The soil, fertilizers, and pesticides eroded by the surrounding waterways are transported via the water to a location different from their former one. These are taken away by the water flow and deposited in the delta area of the river. This delta is a land-form which is formed by the deposition of the similar substances, where the flow of the river is slower.
Hence, the correct answer is 'Option B'.
