Final answer:
A real estate licensee is not performing unauthorized legal work when using contracts promulgated by TREC, which are designed for transactions they are licensed to conduct.
Step-by-step explanation:
A licensee who completes a contract for the sale of real property is not engaged in the unauthorized practice of law if the licensee uses a form that is promulgated by TREC (Texas Real Estate Commission). Occupational licenses, such as those required for real estate brokers, show that a worker has completed specific education or passed a test, and are a means to establish quality in the labor market. These licenses fulfill both a protective function for consumers, ensuring a level of proficiency and knowledge, and offer a way to regulate the industry.
Answer: d) Promulgated by TREC
