Biology

Chlorophyll is the pigment responsible for the green color of plants. It absorbs light energy primarily in the blue and red wavelengths, reflecting green light, which gives plants their characteristic green color.

The other options are incorrect:

The stroma is the fluid-filled space inside the chloroplasts that surrounds the thylakoid membranes. It is where the Calvin cycle (the light-independent reactions of photosynthesis) takes place. It does not contribute to the green color of plants.
