Respuesta :
The answer is phototropism, which is the growth of an organism responding to the presence of light.
Answer: Option (b) is the correct answer.
Explanation:
Phototropism is defined as the ability of a plant to either respond to light or does not respond to light.
When a plant respond to light then it is known as positive phototropism and when a plant does not respond to light then it is known as negative phototropism.
Therefore, when a sunflower turns its head towards sunlight then it means sunflower is responding to light.
Thus, we can conclude that phototropism triggers this behavior in a sunflower.
