Which of the following is a characteristic feature of electrophilic aromatic substitution reactions?

Step 1: Understand that electrophilic aromatic substitution is a type of chemical reaction involving aromatic compounds.
Step 2: Recognize that in this reaction, an electrophile (a positively charged species) attacks the aromatic ring.
Step 3: Learn that when the electrophile attacks, it temporarily disrupts the aromaticity of the ring.
Step 4: Identify that this disruption leads to the formation of a sigma complex, also known as an arenium ion.
Step 5: Note that the sigma complex is a key intermediate in the reaction before the aromaticity is restored.
