Samantha purchased a used computer system from Office Rental Inc. who was updating its computers. Later Big Bank asserted the right to repossess the used computer system from Samantha since it had a lien on all of Office Rental's business equipments that secured an unpaid loan. Samantha was unaware of this lien. What are Samantha's legal rights?

1) She can sue Office Rental for breach of warranty of title.

2) She can claim that she was unaware of Office Rental's debt, and hence Big Bank cannot assert its lien.

3) She can continue to possess the computer system, since she paid Office Renter for it.

4) She can claim a refund from Office Rental but cannot bring a lawsuit against Office Rental or Big Bank
