D The addition product is a frequently observed minor product.
Correct Answer
Correct Answer

Option D is the correct answer.

Detailed Explanation

In electrophilic aromatic substitution, the addition product (sigma complex) is not a frequently observed minor product; it is a reaction intermediate that rapidly loses a proton to restore aromaticity. The other statements are correct.

Hint

Is the addition product a major product in electrophilic aromatic substitution?
