Final answer:
Omission is the deliberate attempt of a broker to withhold or omit pertinent information to all parties in a transaction. Option (B) telling a seller that they can get a higher price for their property than they realistically can is not an example of omission by a broker.
Step-by-step explanation:
Omission is the deliberate attempt of a broker to withhold or omit pertinent information to all parties in a transaction. In this case, the broker is intentionally not disclosing relevant information to either the buyer or the seller. Option (B) telling a seller that they can get a higher price for their property than they realistically can is not an example of omission by a broker. This is an example of providing false information or exaggerating potential outcomes, which is different from omitting pertinent information.
