Final answer:
A listing contract without a termination date is considered a prohibited dealing in real estate as it does not comply with the regulations mandating that a specific expiry date be included in such agreements. The correct answer is option A.
Step-by-step explanation:
The making of a listing contract without a date of termination is considered a prohibited deal. Listing contracts are agreements between a property owner and a real estate broker, wherein the broker is granted the authority to act as the agent for the sale of the owner's property.
The presence of a termination date is crucial as it ensures that the property owner is not indefinitely tied to a broker, and it provides a clear endpoint to the contractual relationship. According to most real estate laws, listing agreements must have a specified expiry date. Therefore, failing to include a termination date does not comply with these regulations and is typically considered a violation of real estate licensing laws, which can lead to disciplinary actions against the broker.
