The correct answer is:
**A. They add oxygen to and remove carbon dioxide from the atmosphere.**
Phytoplankton perform photosynthesis, during which they use sunlight to convert carbon dioxide and water into glucose and oxygen. This process contributes to the oxygen supply in the atmosphere and reduces the levels of carbon dioxide, thus playing a crucial role in both the carbon and oxygen cycles.
