Final answer:
A homeowner listing their house can ask their agent to show the house between certain hours, only show to pre-approved buyers, and have no sign in the yard. However, offering a discount for all military members may violate fair housing laws.
Step-by-step explanation:
The subject of this question is Social Studies. The question is asking about a homeowner listing their house and what they can ask their agent. The options given are a) To show the house between certain hours, b) To only show to pre-approved buyers, c) Discount for all military members, and d) No sign in the yard.
Out of these options, the one that a homeowner cannot ask their agent is c) Discount for all military members. Offering a discount specifically for military members may be considered discriminatory and against fair housing laws in many countries.
It is important for homeowners to be aware of fair housing laws and not discriminate against any potential buyer or tenant based on their status or occupation. If a homeowner wants to offer discounts or incentives, it should be done in a way that is fair and does not violate any laws.
