Options

B. oxygen, water
C. water, Oxygen
D. water, carbon dioxide

Answer

To answer the question "During the day, most plants lose .... and take up....", we can break down the process that occurs in plants during daylight hours.

### Step-by-Step Solution:

1. **Understanding Photosynthesis**: During the day, plants undergo a process called photosynthesis. This is crucial for their growth and energy production.

2. **Taking Up Substances**: In photosynthesis, plants take up carbon dioxide (CO2) from the atmosphere through small openings in their leaves called stomata. They also absorb water (H2O) from the soil through their roots.

3. **Releasing Substances**: As a result of photosynthesis, plants convert the absorbed CO2 and water into glucose (a form of sugar) and oxygen (O2). The oxygen produced is released back into the atmosphere.

4. **Final Answer**: Therefore, during the day, most plants lose oxygen (O2) and take up water (H2O) and carbon dioxide (CO2).

### Conclusion:
The correct completion of the statement is: "During the day, most plants lose oxygen and take up water and carbon dioxide."
