B. `6CO_2 + 12H_2O + "Chlorophyll "+ "Sunlight " to C_6H_12O_6 + 6O_2 + 6H_2O`
C. `6CO_2 + 12H_2O + "Chlorophyll " + "Sunlight" to C_6H_12O_6 + 6CO_2 + 6H_2O`
D. `6CO_2 + H_2O + "Sunlight" to C_6H_12O_6 + O_2 + 6H_2O`

Explanation

To determine the correct representation of photosynthesis, we need to understand the overall chemical equation involved in the process. Photosynthesis is the process by which plants convert carbon dioxide and water into glucose and oxygen using sunlight.

### Step-by-Step Solution:

1. **Identify the Reactants and Products**:
- The reactants of photosynthesis are carbon dioxide (CO₂) and water (H₂O).
- The products are glucose (C₆H₁₂O₆) and oxygen (O₂).

2. **Write the Basic Equation**:
- The skeletal equation for photosynthesis can be written as:
\[ \text{CO}_2 + \text{H}_2\text{O} \xrightarrow{\text{sunlight}} \text{C}_6\text{H}_{12}\text{O}_6 + \text{O}_2 \]

3. **Balance the Equation**:
- Count the number of atoms for each element on both sides of the equation.
- For carbon (C): There are 6 carbons in glucose, so we need 6 CO₂.
- For hydrogen (H): There are 12 hydrogens in glucose, so we need 12 H₂O.
- For oxygen (O): After balancing C and H, we need to ensure that the total number of oxygen atoms is equal on both sides.

4. **Final Balanced Equation**:
- The balanced equation for photosynthesis is:
\[ 6 \text{CO}_2 + 12 \text{H}_2\text{O} \xrightarrow{\text{sunlight}} \text{C}_6\text{H}_{12}\text{O}_6 + 6 \text{O}_2 \]

5. **Select the Correct Option**:
- From the options provided, identify which one matches the balanced equation we derived above. The correct representation of photosynthesis should include 6 CO₂, 12 H₂O, glucose (C₆H₁₂O₆), and 6 O₂.
