Which of the following is NOT a standard form promulgated by TREC?

The correct answer is that an Option Contract is not a standard form promulgated by the Texas Real Estate Commission (TREC). TREC provides specific forms that are widely used in real estate transactions to ensure compliance with Texas laws and regulations. These forms are designed to be used consistently, protecting both the interests of buyers and sellers in real estate transactions.

The Exclusive Right to Sell Agreement, Lease Agreement, and Purchase Agreement are all standard forms promulgated by TREC. Each of these has been specifically developed to streamline the processes of listing properties, renting, and offering to purchase, ensuring that necessary legal protections are included for the parties involved. In contrast, an Option Contract is typically a more specialized agreement and is not included in TREC's standard forms, often requiring custom drafting based on the specific terms agreed upon by the parties. Thus, this makes the Option Contract the correct answer as it does not conform to the standard forms established by TREC.
