Which of the following compounds is an aromatic compound?

Step 1: Understand what an aromatic compound is. Aromatic compounds are special types of chemical compounds that have a ring structure and follow certain rules.
Step 2: Identify the key features of aromatic compounds. They must be cyclic (form a ring), have delocalized pi electrons (electrons that are shared across the ring), and follow Hückel's rule (which states they must have a specific number of pi electrons).
Step 3: Look at the compound in question. Check if it has a ring structure and if the electrons are delocalized.
Step 4: If the compound is benzene, recognize that it has a six-membered ring with alternating double bonds, which means it has delocalized pi electrons.
Step 5: Conclude that benzene is an aromatic compound because it meets all the criteria.
