निम्न में से यौगिक का अणु है

Options

A. `N_(2)`
B. `O_(2)`
C. `Cl_(2)`
D. `H_(2)O`

Answer

To determine which of the given options is a compound, we need to understand the definition of a compound in chemistry. A compound is formed when two or more different elements are chemically combined in a fixed ratio.

### Step-by-Step Solution:

1. **Identify the Given Options**:
The options provided are N2, O2, Cl2, and H2O.

2. **Analyze Each Option**:
- **N2**: This is a molecule consisting of two nitrogen atoms. Since both atoms are of the same element, it is not a compound.
- **O2**: This is a molecule consisting of two oxygen atoms. Similar to N2, it consists of the same element, so it is not a compound.
- **Cl2**: This is a molecule consisting of two chlorine atoms. Again, it consists of the same element, thus it is not a compound.
- **H2O**: This is a molecule consisting of two hydrogen atoms and one oxygen atom. Since it contains two different elements (hydrogen and oxygen) combined in a fixed ratio, it qualifies as a compound.

3. **Conclusion**:
Based on the analysis, H2O is the only option that meets the criteria of a compound as it is formed from different elements (hydrogen and oxygen) in a definite proportion.

### Final Answer:
The compound among the given options is **H2O** (the fourth option).
