The law attempts to help persons who may feel forced to enter contracts. Which of the following is false with regard to the law of undue influence, duress, etc.?

A) An unconscionable transaction is one in which one party has been seriously taken advantage of, and the courts, in their equitable jurisdiction, can set such a contract aside. B) If a contract favours the stronger party in a relationship (e.g., if a lawyer bought property from a client at far below the market value), the court would presume undue influence (i.e., that the stronger party abused his dominant position).

D) A contract entered into because of a threat of violence is voidable at the option of the victim. E) Independent legal advice given to a person who wants to give a gift to a dominant person (e.g., his doctor) is good evidence to rebut a presumption of undue influence.
