The correct answer is D. quality, quantity and duration of light.
Plants need light to grow. The quality of light refers to the type of light, such as red, blue, or green light. The quantity of light refers to the amount of light, such as how bright or dim the light is. The duration of light refers to how long the plant is exposed to light. All of these factors influence plant development.
For example, plants need blue light to produce chlorophyll, which is necessary for photosynthesis. Plants also need red light to promote flowering. The amount of light a plant receives affects its growth rate. Plants that receive more light will grow faster than plants that receive less light. The duration of light also affects plant development. Plants that are exposed to more light will have longer stems and leaves than plants that are exposed to less light.
In conclusion, plant development is influenced by the quality, quantity, and duration of light.
