The question asks for the total number of aromatic compounds among the given compounds, but the actual list/structures of the compounds is missing from the prompt.

Without the compounds, it is impossible to determine how many are aromatic.

What is needed

To solve this, I need the structures or names of the compounds shown in the original question.

Aromaticity criteria

A compound is aromatic if it satisfies all of the following:

1. It is cyclic.
2. It is planar.
3. It is fully conjugated (continuous overlap of p-orbitals).
4. It follows Hückel’s rule, i.e. it has $(4n+2)\pi$ electrons, where $n=0,1,2,\dots$

Examples:

• Benzene: aromatic, $6\pi$ electrons
• Cyclobutadiene: antiaromatic, $4\pi$ electrons
• Cyclooctatetraene: non-aromatic (non-planar)

Comparison with stored answer

Since the compounds themselves are not provided, I cannot independently verify whether the total number is $1$.

Please upload or type the compounds/figure, and I will solve it step-by-step and compare it properly.
