Scrooge McDuck purchased a house and promised to pay Daisy Duck her broker's commission. Scrooge McDuck failed to make this payment and Daisy threatened to sue Mr$.$ McDuck. To keep Daisy from filing a lawsuit, Mr$.$ McDuck promised to pay what was owed plus an additional $5\%$ if Daisy would not exercise her legal right to sue him in this case. Later on$,$ Mr$.$ McDuck refused to pay on the grounds that there was no consideration from Daisy. Which of the following is true?

None of these answers.

Daisy's consideration in this case was forbearance because Daisy did not sue on the original contract.

Daisy's promise to not sue was not legally sufficient as consideration.

Scrooge McDuck will be able to prove that promising not to sue in the future is speculative and he does not owe the additional $5\%.$
