Which one of the following is a benzenoid aromatic compound ?

Options

A. Furan
B. Thiophene
C. Pyridine
D. Aniline

Explanation

To determine which of the given options is a benzenoid aromatic compound, we need to understand the definition of benzenoid aromatic compounds and identify the structures of the compounds provided.

### Step-by-Step Solution:

1. **Understand the Definition**:
- Benzenoid aromatic compounds are those that contain a benzene ring or a structure that is derived from benzene. They exhibit aromaticity due to the presence of a cyclic, planar structure with delocalized π electrons.

2. **Identify the Options**:
- Let's consider the compounds mentioned: furan, pyridine, and aniline. We need to analyze each of these to see if they contain a benzene ring.

3. **Analyze Furan**:
- Furan is a five-membered ring with oxygen as one of the atoms. Its structure does not include a benzene ring. Therefore, furan is classified as a non-benzenoid aromatic compound.

4. **Analyze Pyridine**:
- Pyridine is a six-membered ring containing one nitrogen atom. While it is aromatic, it does not have a benzene structure. Thus, pyridine is also a non-benzenoid aromatic compound.

5. **Analyze Aniline**:
- Aniline consists of a benzene ring attached to an amino group (-NH2). The presence of the benzene ring means that aniline is a benzenoid aromatic compound.

6. **Conclusion**:
- Among the options provided, aniline is the only compound that qualifies as a benzenoid aromatic compound.

### Final Answer:
- Aniline is the benzenoid aromatic compound.
