Final answer:
If Jamie authorizes Amy to sell his house without clarifying compensation, Amy should not expect to be paid anything.
Step-by-step explanation:
In this case, since Jamie did not specify any compensation for Amy, the correct answer would be option a. Nothing, since agency relationships are assumed to be gratuitous unless an agreement specifies compensation. Agency relationships are generally considered to be voluntary and unpaid, unless otherwise agreed upon. Therefore, Amy should not expect to be paid any amount for selling Jamie's house.
