Final answer:
Statement D represents the unauthorized practice of law, as it involves an agent offering legal advice without being licensed to do so.
Step-by-step explanation:
The statement that may represent the unauthorized practice of law is: D. An agent saying, "You should proceed without ordering a new abstract - this title is clear." Providing advice on legal matters such as the status of a title, without being authorized or licensed to practice law, may constitute unauthorized legal practice. Statements A, B, and C, however, describe activities that are typically within the normal scope of practice for those in legal professions, assuming all necessary conditions such as licensure and appropriate supervision are met.
In A, an attorney advising a client is exercising their professional role, in B, a paralegal is performing duties under an attorney's supervision, and in C, a notary public is carrying out a role that does not constitute practicing law.
