Under conditions of low transpiration, absorption occurs through active absorption. When transpiration rate is high water is absorbed passively under the influence of transpiration pull. According to root pressure theory, water rises upwardly in the xylem due to positive pressure developed in the root. This positive pressure develops by active transport of minerals ions by roots. Thus, the correct answer is option B.
