### Thoughts


I found this question quite tricky and confusing. According to my concepts and logic


* **3** should be non-aromatic, while **1** and **2** are antiaromatic.
* Also there is a lone pair repulsion in **2**.


After racking my brain I up came with the answer of **3** > **1** > **2** (arguably most convincing for me), which is wrong according to the actually given answer.


So, while my answer for **1** > **2** is correct, I still have no explanation for **3**.


Kindly help me on what I am missing or if I am wrong somewhere.
