C) Pot A received more sunlight than pot B.

Explanation:

Plants are autotrophic beings, that is, they produce their own food from inorganic compounds. This occurs through photosynthesis, in which plants use carbon dioxide and water to synthesize glucose. Photosynthesis will allow plants to produce the molecules necessary for their development and healthy growth.

However, in order for this process to occur, plants need sunlight, as it is the energy that enables the occurrence of fundamental chemical reactions for photosynthesis. Chlorophyll is a pigment that gives plants a green color and it captures light energy, which is the first step in enabling photosynthesis.

If the plant is kept out of sunlight, inside a cabinet for example, it will not be able to start photosynthesis and will not be a strong and healthy plant, even if it has access to quality water and soil.

kelp are large brown algae that live in cool, relatively shallow waters close to the shore. they grow in dense groupings much like a forest on land. these underwater towers of kelp provide food and shelter for thousands of fish, invertebrates, and marine mammal species.
