{'plant cells': [1, 0, 1, 3], 'cytokinin': [1, 0, 1, 2], 'auxin': [1, 0, 1, 2], 'hormones': [1, 0, 2, 2], 'gibberellin': [1, 0, 1, 2], 'abscisicacid': [1, 0, 0, 1], 'light': [16, 4, 34, 62]}

The correct answer is option 2: Auxin.

Auxin is a hormone that stimulates plant cells to grow in a manner that causes the plant to bend or curve towards a source of light. This process is known as phototropism.

Option 1: Cytokinin is a hormone that promotes cell division and growth in plants, but it does not specifically influence the bending of plants towards light.

Option 3: Gibberellin is a hormone that regulates various aspects of plant growth and development, but it does not have a direct role in phototropism.

Option 4: Abscisic acid is a hormone that is involved in regulating plant responses to stress and dormancy. It does not influence the bending of plants towards light.

Therefore, the correct hormone that stimulates plant cells to grow in a way that causes the plant to bend towards light is auxin.
