Answer:
Answer is Option B: that she was under undo duress from her son and daughter-in-law and that the agreement is voidable.
Step-by-step explanation:
When the broker came to offer Mrs. G, the price he offered was quite less than what she was asking for. Still his son and his wife urged her to sign the offer. So, later she can claim that she was under a lot of threat and violence from her son and daughter-in-law to sign the offer and it would make the agreement voidable.
She cannot claim about Broker's offering less price, as per Option A. Neither she can say that Broker defrauded them, as per Option C. Option D is also incorrect as it says that her consumer rights were taken illegally by her son and his wife.
