All of the following have a restricted ability to enter into a contract EXCEPT:

Virginia contract law, reflected in Virginia Code § 38.2-102, requires capacity to form an insurance contract. Option A (intoxicated individuals) lacks capacity if impaired, voiding consent. Option B(mentally ill individuals) may lack comprehension, restricting ability unless adjudicated competent. Option C (minors, typically under 18 per § 38.2-3405) can’t contract without guardian consent, except for necessities. Option D (retired individuals) has no legal restriction; retirement is a status, not a capacity limiter—e.g., a 65-year-old retiree can buy insurance freely. The study guide likely covers capacity in a legal basics section, with examples like a drunk person’s void policy versus a retiree’s valid one, making D the exception.
