Solution
The correct option is A Increase Auxin is a plant hormone that plays important role in plant growth. It stimulates stem elongation by increasing permeability of cells which in turn increases uptake of water by cells. It also increases the respiration rate. When auxin concentration is increased in roots, it will increase permeability of root cells and hence water absorption will increase.
