A person who is unable to read is bound by signing a contract without obtaining an explanation of it, unless:

a. the other contracting party later becomes aware of the signer's inability to read.

b. the other party is similarly lacking in education.

c. the other contracting party knows of the signer's disability.

d. none of the above; an illiterate person is always bound by a contract he or she chooses to sign without obtaining an explanation.
