The correct summary of photosynthesis is

Options

A. `6CO_(2) + 6H_(2)O +" light" to C_(6)H_(12)O_(6) + 6H_(2)O + 6O_(2)`
B. `6CO_(2) + 12H_(2)O + "light" to C_(6)H_(12)O_(6) + 6O_(2) uarr + 6H_(2)O`
C. `C_(6)H_(12)O_(6) + 6O_(2) + 6H_(2)O + "light" to 6CO_(2) uarr + 12H_(2)O`
D. `6CO_(2) + 6H_(2)O + "light" to C_(6)H_(12)O_(6) + 3O_(2) uarr + 6H_(2)O`

Answer

**Step-by-Step Solution:**

1. **Understanding the Photosynthesis Equation**:
The process of photosynthesis can be summarized by the chemical equation:
\[ 6 \text{CO}_2 + 6 \text{H}_2\text{O} + \text{light energy} \rightarrow \text{C}_6\text{H}_{12}\text{O}_6 + 6 \text{O}_2 \]
This indicates that six molecules of carbon dioxide (CO₂) and six molecules of water (H₂O) react in the presence of light to produce one molecule of glucose (C₆H₁₂O₆) and six molecules of oxygen (O₂).

2. **Analyzing the Options**:
- **Option 1**: 6 CO₂ + 6 H₂O → Glucose + 6 H₂O
- This option incorrectly states that water is an end product, which it is not.
- **Option 2**: 6 CO₂ + 12 H₂O → Glucose + O₂ + 6 H₂O
- This option incorrectly states that 12 molecules of water are used, which is not correct. The correct number is 6.
- **Option 3**: Glucose + O₂ + H₂O → CO₂ + H₂O
- This option describes cellular respiration, not photosynthesis, and is therefore incorrect.
- **Option 4**: 6 CO₂ + 6 H₂O → Glucose + 3 O₂
- This option incorrectly states that only 3 molecules of oxygen are produced, while the correct number is 6.

3. **Identifying the Correct Option**:
After analyzing all the options, it is clear that none of the options accurately represent the photosynthesis equation. However, the closest option that aligns with the principles of photosynthesis is Option 2, which states that 6 CO₂ and 12 H₂O are involved, but it is misleading due to the incorrect number of water molecules.

4. **Conclusion**:
The correct summary of photosynthesis is:
\[ 6 \text{CO}_2 + 6 \text{H}_2\text{O} \xrightarrow{\text{light}} \text{C}_6\text{H}_{12}\text{O}_6 + 6 \text{O}_2 \]
Therefore, the answer is Option 2, with the understanding that it contains inaccuracies.
