Which one of the following statement  is true:

 

 

Lithobenzene, often known as phenyllithium, is an organometallic compound with the empirical formula C6H5Li. It is most frequently employed in organic synthesis as a metalating agent and as a Grignard reagent alternative for the introduction of phenyl groups. Aromaticity is a characteristic of conjugated cycloalkenes that increases a molecule's stability by causing the electrons in the - orbitals to delocalize.
The rules that the aromatic compounds are claimed to follow, or distinctive features, are as follows:
1.Cyclic structures are a feature of all aromatic molecules.
2. To be considered a planar molecule, each element of the ring in the structure must and should have a p-orbital ring that is perpendicular to the ring.

3. All compounds adhere to Huckel's Rule, which states that all aromatic compounds must have (4n+2) electrons.
4. The organic substance must be level.
