This is not a valid scientific question because there are no scientific parameters to test it. So the correct option is B.

What are the factors affecting plant growth?

Plant growth is synonymous with the environmental conditions in that they are present. There are various factors that affect the growth of plants.

The presence of abundant light is one of the factors that affect the growth of plants. Light is required for the process of photosynthesis which provides the plants with the required nutrients.

The presence of a specific kind of soil is also important for the growth of specific plants. The soil needs to be richly supplied with nutrients to support plant growth.

Along with nutrients, plants also should have enough amount of water which also helps the plants in various ways.

The right kind of atmosphere is also required for the growth of plants. Plants require carbon dioxide for photosynthesis and oxygen for respiration. These gases should be available to plants.

Therefore the correct option is B.
