Three people own a house as joint tenants. One co-tenant executes a promissory note secured by a deed of trust against her interest in the house. Which of the following statements is true?

Select one:

a. This defeats one of the unities required for joint tenancy.

b. This creates a security interest in all other properties owned by the borrower.

c. This places the beneficiary in a precarious position, since the lien created by the deed of trust will be extinguished upon the death of the borrower.

d. This invalidates the promissory note because the co-tenant only had a partial interest in the property.
