Solution

The correct option is A Thimann and Kramer
Non-osmotic active water absorption was proposed by Thimann. This theory was given by Thimann (1951) and Kramer (1959). According to the theory, sometimes water is absorbed against the concentration gradient. This requires an expenditure of metabolic energy released from respiration of root cells.
