Answer 2

Option (A) is the answer.

For the ring to be aromatic, it must be planar. The propensity to be planar decreases with the amount of attached rings or carbon atoms.

As a result, option A, the smallest of them, is probably best described as aromatic.

Four Essential Guidelines for Aromaticity:

1. Determining whether a molecule is cyclic is rather simple. If a ring exists, go to the second criterion; otherwise, it is not aromatic.

2. A continuous ring of p-orbitals around the ring that expands into a bigger cyclic "pi system" is also required. This means that any atom near the ring must be able to conjugate with another atom.

3. All of the atoms in the ring must be conjugated.

4. The molecule needs to be flat (planar).
