उत्तर
The plant hormone whose concentration stimulates the cells to grow longer on the side of the shoot which is away from light is Auxins.
Explanation:
Auxins are plant hormones that accumulate on the shaded side of a shoot, stimulating cell elongation and causing the shoot to bend towards the light (phototropism). Other options are incorrect as they do not regulate directional growth in response to light.
