A Correct answer
Explanation

The raised water table results in the soils becoming water-logged. When soils are water-logged, air spaces in the soil are filled with water, and plant roots essentially suffocate - lack oxygen. Waterlogging also damages soil structure. So, the soil becomes physiologically dry.
